How to use PIN instead of passwords for Login in Windows 8

Entering your full password on a touch screen device can really become a pain in the *** , luckily for us we can link a short 4 digit PIN to our user account and log in with that instead.

Note: PIN codes are nowhere near as safe as using an alphanumeric password, however, they do still have a purpose when you don’t want to enter your 15 character password on a touch screen device.

Creating a PIN

Press the Win + I keyboard combination to bring up the Settings Charm, then click on the Change PC settings link.
This will open up the Modern UI PC Settings app, where you can click on the Users section.
On the right hand side you will see a Create a PIN button, click on it.
Now you will need to verify that you are the owner of this user account by entering your password.
Then you can choose a PIN, remember that it can only contain digits.
Now when you get to the login screen you will have the option to use a PIN.

Use KeyRocket to become a master of keyboard shortcuts

Use of keyboard shortcuts can incredibly improve your productivity but it’s difficult to find all the keyboard shortcuts at one place and remember all of them at once. KeyRocket helps you to learn new shortcuts as you do your work. For example if you are working in Word and using your mouse every time when you need to make some text bold. It will notice and suggest you the keyboard shortcut for this.

It also allows you to search shortcuts. Suppose you remember a shortcut combination but don’t know what is it used for, you can use KeyRocket’s library to search shortcuts. KeyRocket silently sits in the background and will suggest you through notifications whenever it has any suggestion. Currently it has shortcut suggestions for Windows Explorer and Microsoft Office suite.

It supports Windows XP, Vista and Windows 7 operating systems. You can download it using the link given below.

How To Create Your Own Custom Google Search Engine

noreply@blogger.com (Anindya) — Mon, 08 Oct 2012 04:05:00 +0000

How To Create Your Own Custom Google Search Engine

Creating a Custom Search Engine

To get started, head over to the Google Custom Search Engine page and click the Create a custom search engine button. You’ll need a Google account for this – the search engine will be saved with your Google account.

Enter a name and description for your search engine – these can be anything you like.

The Sites to search field is the one that really matters. Here, you’ll specify a list of the websites you want to search. For example, if you wanted to search both anindya-nandi.blogspot.com and microsoft.com, you’d enter:

anindya-nandi.blogspot.com/*
microsoft.com/*

The * character is the wildcard, which can match anything, so the /* characters tell your search engine to search everything on both of these websites.

There are more advanced things you can do with this box – we’ll get back to that in a bit.

After clicking Next, you can specify a style for your search results and test the search engine you created.

Once you’re happy with your search engine, click the Next button at the bottom of the page and you’ll end up at a page that gives you an embed code for your search engine.

You’re probably not a web developer, so you’ll want to ignore this page. Click the Google Custom Search logo at the top of the page instead.

To get to your search engine’s page, click its name in the list of search engines you’ve created.

You can bookmark this page for easy access your search engine. You can also share your search engine with anyone by sending them the full URL that appears in your address bar.

Once you’re done, you can even add your custom search engine to your browser’s search bar.

Now you will need to search for:

browser.preferences.inContent

When you find it, right click on it and select Toggle from the context menu.

Next you will need enable the actual PDF Reader feature, you can do this by searching for:

pdfjs.disabled

That’s all there is to it, you can even drag PDF files on your local machine on t0 the Firefox windows to view them!

Note: You will need to disable the Adobe addon after you have completed this.

HTTP Error Codes and Their Meaning

noreply@blogger.com (Anindya) — Sun, 30 Sep 2012 08:03:00 +0000

HTTP Error Codes and Their Meaning

      While surfing the net we always get some HTTP Errors. These Error codes are crucial for troubleshooting various issues. You can see these error codes in various logs.

Installing Android SDK

noreply@blogger.com (Anindya) — Wed, 15 Aug 2012 14:29:00 +0000

Installing Android SDK

In most cases, when you connect an Android device to your computer for the first time, the drivers will automatically be installed. However, the phone will most likely be detected as a mass storage device, not as an Android device. This gives it similar properties as an external hard drive, and should be fine for most users, since you will still be able to copy files to and from your device.

However, if you need to “debug” your Android device (one of the requirements for rooting), you will need to make sure the computer recognizes it as an Android device. Since there is such a great variety of Android devices, there is no single solution for installing the drivers. This guide should work for most devices, but might not work for all.

Installing the drivers using the Android SDK (recommended):

1. Download the Android SDK.

2. Double-click the downloaded file to run it, and follow the on-screen instructions to install the SDK. Make sure you change the installation directory to “C:\android-sdk\”.

3. Run the SDK manager. You will be presented with the following screen:

4. From here, select the following 3 items (and uncheck all others):
         Tools/Android SDK Tools (might already be installed)
         Tools/Android SDK Platform Tools
         Extras/Google USB Driver Package

5. Click on “install packages”. On the window that opens, click on “Accept All”, and then “Install”.

6. Make sure your Android device is in USB debugging mode (Settings -> Applications -> Development), and connect it to your PC. Hopefully the right drivers will now be installed.

7. To test whether the installation was successful, type the following text into notepad, and save as “test.bat”:
cd c:\android-sdk\platform-tools\
adb devices
pause

8. Double-click the file that you just created. If the driver installation was successful, you should see the text “List of devices attached”, followed by a serial number. If this is not the case, you can try to install the drivers using PDANet.

Installing the drivers using PDANet:

1. Download PDANet. Select either the 32-bit or the 64-bit version, depending on your computer’s operating system.

2. Double-click the file and follow the on-screen instructions to install PDANet. If Windows prompts you with the message “Windows can’t verify the publisher of this driver software”, simply click “Install this driver software anyway” (you may be prompted more than once).

3. The drivers for your phone should now be installed (you can test with the same method as mentioned above). If you don’t need PDANet (it’s for tethering your phone) you can simply uninstall it. The drivers will remain installed.

Hide a file behind Image without Any Software

noreply@blogger.com (Anindya) — Mon, 30 Jul 2012 02:45:00 +0000

Hide a file behind Image without Any Software

This was posted by me on 26 Feb 2010. Re-posting it as requested by readers of this blog:

To hide data in an image you need winRAR. First you add file into a rar archive as Secret.rar.

Now copy secret.rar file to a new folder.

Now copy any image u want and paste it in folder of rar file as anyname.jpg. (You can use any other picture file type like .gif, .png etc)

Now open MS-DOS, go to the folder that contains secret.rar file and the image file and type
"copy/b anyname.jpg + secret.rar output.jpg" (without quotes).

You'll now see an image called output.jpg in secret.rar's folder.

Open it with WinRar. Only winrar can open the secret file in it. This can be opened by changing the extension to .rar.

Command prompt to reveal Hidden Files

noreply@blogger.com (Anindya) — Thu, 01 Dec 2011 13:41:00 +0000

Command prompt to reveal Hidden Files

Some viruses leave behind nasty side effects, even when your antivirus program has cleaned the actual virus from your computer. If your desktop icons are missing and your C: drive appears blank, don’t panic — your files haven’t gone permanently AWOL. Common viruses, such as the Windows 7 Recovery virus, will hide your files in an attempt to coerce you into paying for the virus’s removal. When you view your desktop or click on your C: drive, it may appear that all of your files have been deleted, but they haven’t — the virus has simply hidden them. You can restore them easily using a simple command prompt trick that works in Windows XP, Vista and 7.

Click the Start button in the lower left corner of your task bar. Type cmd in the search box at the bottom of the menu and press Enter. If you’re using Windows XP, click Run and type cmd into the Run box.

Type attrib -s -h -r c:/*.* /s /d and press Enter to execute the command. The command prompt window should look like this after you’ve typed the command:

Allow the command to finish executing (it may take a few minutes). When it’s done, close the command prompt window and check your desktop — your files, hidden by the virus, have been restored. You can use the same trick to restore files the virus may have hidden on other drives, including removable storage such as flash drives and external hard drives; just change the drive letter in the command above to the drive letter of the storage device with the hidden files.

How to Zip

noreply@blogger.com (Anindya) — Thu, 01 Dec 2011 11:59:00 +0000

How to Zip

Say you have many files that all need to be e-mailed, but you don’t want to add them one by one and you don’t think all of them will be within the recipient’s e-mail size limits.

What do you do then ? Why zip ‘em up, of course!

So....here is how to do it in a flick of a second .........

Browse to the folder where the files you want to zip are at. Now highlight the files by either drawing a box around them or by holding the Ctrl key and selecting each of them. Once you have all of the ones you want to zip up highlighted, Right-Click one of them, go down to “Send to” and choose “Compressed (zipped) folder”.

Like magic, your highlighted files will appear in one convenient package. If you don’t like the name Windows gives your zipped folder, just rename it!

If you don’t want to use the built-in Windows zip utility, there are also third-party programs like WinZip and WinRar, that have more features, like the ability to set the compression size and file extension.

Start Internet Explorer 9 in Private Mode

noreply@blogger.com (Anindya) — Sat, 26 Nov 2011 18:13:00 +0000

Start Internet Explorer 9 in Private Mode

For all you Internet Explorer 9 users out there, how would you like to learn a quick trick so that every time you start IE, it runs in Private mode right from the start ?

What we’re going to do is create a desktop shortcut for IE and set a switch to make it start in InPrivate mode. So, right-click on your desktop, select New and choose Shortcut.

Now, if you’re using a 32 bit version of Windows, copy this text and put it in the path box:

“C:\Program Files\Internet Explorer\iexplore.exe” -private

For those out there running 64 bit windows, you have to change it a bit. Use this line:

“C:\Program Files (x86)\Internet Explorer\iexplore.exe” -private

Notice that in both cases we put -private after the quoted path.

When you’re done, hit Next, give your shortcut a name and you’re good to go.

Note: if you get an error while inputting this path, you might have a different version of windows and should try the other path.

Auto-Complete commands in Win 7 Command Prompt

noreply@blogger.com (Anindya) — Sat, 26 Nov 2011 16:50:00 +0000

Auto-Complete commands in Win 7 Command Prompt

Did you know that there’s a way to auto complete a path or file name in the Windows 7 Command Prompt?

Here’s how!

Open a Command Prompt by clicking Start, then typing cmd in the Search Box. Right Click the Command Prompt icon in the results that appear and select Run as Administrator.

In the Command Prompt window, type in the change directory command, like this:

Now hit the Tab key.

*Poof* -the path is completed!

If you keep pressing the Tab key, the Command Prompt will put forth the next applicable file or folder that’s consistent with what you’ve typed so far.

Note: This may not work if you don't open the prompt as Administrator

What are Pen Flicks in a Touch screen Laptop

noreply@blogger.com (Anindya) — Wed, 23 Nov 2011 17:35:00 +0000

What are Pen Flicks in a Touch screen Laptop

I think the reason people love touch screens is because of how natural the hand gestures feel. For example, to scroll down a document, it feels better to just swipe down instead of pressing a little arrow key. If you’re looking to bring some of these intuitive gestures to your Windows computer, then might I humbly recommend that you enable Pen flicks.

To utilize pen flicks, your computer must be touch screen, or your laptop’s trackpad must support gestures. If you have a graphics tablet, then that will also allow pen flicks as well.

Begin by pressing the Start button, and selecting Control Panel.

Select the Classic view, and double click Pen and Input Devices.

Now choose the Flicks tab, and check the box labeled Use flicks to perform common actions quickly and easily.

Now you have two options: the navigation flicks, or the navigational flicks with editing. I personally prefer the latter, as it allows me to copy and paste with ease. Choose the option that best suits you, and of course, you can always change this setting.

If you select Customize, you can hand select what action a flick in a certain direction will perform. If you’d like to add a custom keyboard shortcut, just select the add option. For example. I made it so that a downward flick will close the program using the keyboard shortcut Alt+F4.

Finally, one last setting I’d like to bring to your attention is the flick sensitivity. If you find that you have to repeat a gesture several times before Windows recognizes it, then you should make the sensitivity more relaxed. However, if you find gestures are occurring by accident, than you should move the slider to the precise setting.

I hope this setting makes your computer feel a little bit more natural. Enjoy!

Network problems and Command Prompt

noreply@blogger.com (Anindya) — Tue, 22 Nov 2011 06:08:00 +0000

Network problems and Command Prompt

You don’t have to be an IT expert to troubleshoot pesky network and Internet connection problems. All you need is the Command Prompt utility. Any computer users familiar with MS-DOS and Windows 3.1 recognize it. Well, that utility hasn’t gone away; it’s still around, just hidden in the background.

Here’s how to access it, and how to troubleshoot basic network problems from your computer.

Press the Windows key on your keyboard. Type the text cmd in the search box – in XP this is called “Run” – and press Enter.

Basic rule of troubleshooting: always start with the closest possible source. You need to check your own computer for network connectivity first. Type ping 127.0.0.1 and press Enter. Your Command Prompt window should look like this if your computer’s network card has no problems:

You’ve just sent four requests for dummy data to your computer’s “loopback” IP address and it (hopefully) replied to each one. An IP address is a unique tag for your computer that tells the server where to send data; the loopback address is used for testing your computer’s network card. If there were intermittent problems or if your card were completely non-functional, the ping would have experienced some loss.

The next step up the chain is your default gateway, which is in most cases the network router. Any data entering or exiting the network has to pass through the router. To diagnose the router, you need to ping its IP address. Type ipconfig at the command prompt and look for the entry next to “Default Gateway.”

Now, ping your router the same way you pinged the loopback address: type ping . In this example, you’re pinging the default gateway at 10.0.0.1. If the connection between your computer and the router is strong and stable, all four of your data packets should get a response. If not, your router has connectivity problems. As a note, wireless connections are prone to drop signal, so keep that in mind when working with a wireless router.

Let’s say you’ve tested your computer and router and that everything checks out, but you still can’t connect to a webpage. So, perform the ping test on it. Let’s use Yahoo! for an example:

Yahoo! works. Just to be sure, do another ping test, this time to Google:

Google’s homepage checks out. If you were able to ping two remote sites successfully, you don’t have a problem with your network or Internet connection.

What is 32 Bit and 64 Bit - Explained

noreply@blogger.com (Anindya) — Tue, 22 Nov 2011 02:46:00 +0000

What is 32 Bit and 64 Bit - Explained

In one context, 32-bit and 64-bit refers to how a CPU (computer processor) handles information. These terms also indicate the number of bits that comprise a single data element (for example, a pixel in an image). In that case, when dealing with resource hogging data like images, audio, or video, there is a distinct advantage to a 64-bit system. However, when writing emails or text documents, the benefits of 64-bit may be less apparent.

What is a bit?

A bit (short for binary digit) is the smallest unit of digital information, represented by either 0 or 1. Arranging a series of bits in sequence creates a binary math language that the processing chips can understand. As a result, CPUs are identified by their ability to process these sequences (32-bit or 64-bit). Eight consecutive bits in such a sequence equals a byte (short for binary term). Large numbers of bytes are then combined to create kilobytes, megabytes, gigabytes, terabytes, etc.

Not confusing enough?

The terms, 32-bit and 64-bit indicate the width of the registers, which are storage areas within the computer. The registers can contain either the address location in the computer memory where data is stored, or the data itself. All computer data is processed using information represented in these registers.

Each instruction (the most basic computer command) can process the number of bits indicated in the registers. So, a 64-bit machine processes a 64-bit width register with each instruction. Likewise, a 32-bit machine processes a 32-bit width register per instruction. While it would seem that a 64-bit processor would naturally be faster, the number of instructions executed per cycle (the fundamental unit of time measurement in a device) indicates actual processing speed, so that may not always be the case.

It’s the combination of hardware and software elements which make up the computer architecture that determines processing speed. This will be discussed in part two of this series, where we’ll take a more in-depth look at processors, memory, and how hardware and software interact to improve (or–if not correctly balanced–reduce) overall performance.

Speed

Processing speed, referred to as clock speed, is generally measured in megahertz (MHz) which amounts to one million cycles per second, or gigahertz (GHz) equaling one billion cycles per second.

A computer’s architecture is a significant contributor to that processing speed, so CPUs (computer processors) with the same clock speed may not perform functions at the same rate. While a fixed number of clock cycles is required for each command (instruction), a faster clock will execute more instructions per second, and the machine will perform those instructions more quickly.

However, clock cycles (or clock ticks), like so many other terms in this bewildering lexicon jungle, is a term with multiple meanings. On one hand, a clock cycle is as described above, the relative speed of a processor, but it also refers to the internal system clock, which always runs at 66 MHz (66 million clock ticks per second). So, more powerful CPUs can execute instructions more rapidly than their less sophisticated counterparts, while still displaying the same number of units per cycle.

Memory

While the clock speed of the CPU is the primary indicator of processing capability, RAM (Random-Access Memory) also plays a significant role in performance. When a CPU requests information from the hard drive, it’s put into RAM, where it can be accessed with greater efficiency. But, if the memory (RAM) isn’t sufficient, the information may have to be returned to the hard drive before the next request can be answered, thereby slowing overall performance.

Hardware and Software

Hardware and drivers (the software that controls the hardware) must match the device’s system type, and this should be a primary consideration when upgrading a 32-bit system.

What all this means is that, with each operation, 64-bit processors can handle bundles of information that are twice the size of those processed by 32-bit systems, and the speed at which these bundles are delivered is determined by the overall balance of system resources (RAM, processors, etc.). In researching this article, I was directed to an analogy of a two lane highway that had been converted to a four lane highway to relieve bottlenecks. But, while that’s a good comparison, the benefit is more than just a method of efficiently moving traffic. 64-bit is not just an increased amount of data per bundle, it’s also higher quality data, as images, audio, and video files comprised of 64-bit elements are richer, with more depth and texture, than those made up of 32-bit elements.

The next and final part of this article, How to Determine if a System is 64-Bit Capable, will explain how to tell whether a system is 32-bit or 64-bit, and whether upgrades are possible (or practical).

I hope this has been as enlightening to read as it was to write.

Speed Up Google Chrome

noreply@blogger.com (Anindya) — Sun, 20 Nov 2011 17:10:00 +0000

Speed Up Google Chrome

Well Google lunched new version of Google chrome which is much faster and stable, You also loving it and it’s becoming your favorite browser as you simply loves it’s clean interface and speed of browsing. Here are some good tips which can improve your experience further and you will love this fantastic browser more than ever.

Just follow these tips and see how Chrome improves in performance -

Disables usage statistics of Google Chrome

This option is used to help in Development of Google chrome, It send your usage data to Google so that based on that they can further improve Chrome. But if you are worried about system performance you should disable it . To disable this go to tools menu > Options > Advanced and uncheck the check box which says Send usage data to Google….

Disable DNS Preload in Google Chrome

This will prevent Google chrome to keep DNS info in their cache. Most of time it is unnecessary if you have a good connection of at least 256kbps or more. It is recommended only for slow dial up connection or Mobile users who actually spend a lot f time in DNS query during browsing. to disable this select tools menu of Google Chrome and select “Options.” In the next window, go to the “Advanced” tab and uncheck the “Use DNS preload ….”

Disable anti-phishing filter

If you are advanced web user and you know how a phishing site look like or you know how to prevent from them you can disable this option. But if you are not at all comfortable working without phishing filters or don;t want to take risk you should keep it as it is . Disabling this not only saves your CPU time but also save your Internet bandwidth. This option can also be disabled from Tools Menu > Options > Advanced.

Removes navigational data regularly

All of the browsers cache the Navigation data and other info for faster access to web pages you frequently visit. But if your cache size is big or it contains very old pages which you hardly visit once or twice in a month it will start performing negative for you, as web pages will load faster but they Browsers perform worse when navigation data is saved. So it is important to remove navigational data frequently. To delete this in Chrome, go to Tools menu and choose the option “Remove navigation data” and choose “Delete data for this period” and not the option “All”. So it will remove old data and will keep recent data do this once in a week at least.

Disable Useless function which we don’t use normally –

To options that are mentioned below you need to edit the properties of Chrome shortcut which you are using to start the browser. To Change it, right click on the Chrome icon and choose “Properties.” this will open a windows with the “Shortcut” tab, in this tab there is a box called “Destination”. You have to change things in this box itself.

E.g. To disable Java box,

if you are using Windows Vista it should go like this — : “C:Users\AppDataLocalGoogleChromeApplicationchrome.exe -disable-java”
and if you are using Windows XP: “C:Documents and Settings%username% Local SettingsApplication DataGoogleChrome.exe”

The options which we are adding after the full path of chrome can be used one after the other leaving a space between. You don’t need to write the entire path every time you are using a new options. Here are the option which can be used -

Disable-dev-tools – This will disable Developers tool which is not used by a normal user for sure.

Disable-logging – This will disable looging of browser activity, This log files are useful only in case of Crash or Other error which prevent you from using browsers. if you are experiencing any such problem and need to know the reason you can enable this option. but in general you don’t need these log files. By disabling this you will certainly save CPU RAM and Hard disk space.

Disable-metrics-system – This option will disable gathering of Usage Statistics data. This is used by Google and we don’t need it any how so you can safely disable this option.

Disable-metrics-reporting – If you disabled Metrics system there is no point in keeping Metrics reporting On, as there won’t be any data to send across. Disable it for sure.

Disable-java – Java on the web is rarely used these days and it greatly slow downs your browsers performance. If you not running any online application which uses Java or Java Applets you can safely disable this feature. This will prevent you from playing number of Online Java Games though. (like Yahoo Games)

Disable-java script – This will disable all kinds of JavaScript from being run on the web pages you visit. This is not recommended at all as most of the sites these days are using some kind of JavaScript, to display pages. By Disabling JavaScript you will not be able to see these site properly and they will behave improprly. This is why disabling JavaScript is not recommended.

Disable-plugins – This will disable all plugins including Flash player and other media player. After applying this modification you won’t be able to see a lot of media sites properly including YouTube. If you understand impact of disabling this go ahead and do it otherwise don;t use this option.

Disable-images – This will disable all images on all Webpages you browse, if you are using low bandwidth conection like GPRS or Dial Up it will be very useful for you as it will save a lot of bandwidth for you. This will make your browser an text only browser. So be sure you need it that way before making these changes.

How to hide usernames in Windows 7

noreply@blogger.com (Anindya) — Sun, 20 Nov 2011 17:05:00 +0000

How to hide usernames in Windows 7

The login screen of Windows Vista and Windows 7 makes it very easy to see the user name of the last person that logged in. This may be fine on personal computers, but on shared computers, this could be a security threat. A potential intruder would only have to find out the password, which is very possible with the right software. To solve this problem, we have to change a value in the registry. Don’t worry; it is easier than it sounds. But before we change anything, it is best to make a backup of the registry.

Note: If you’re uncomfortable editing the Windows Registry do not attempt this tip.

1. Press [Windows Key] + R to bring up Run.

2. Type “regedit” (without quotes) into the text box and hit enter.

3. In the Registry Editor, click on File -> Export…

4. Enter “backup” (without quotes) as name and save the file to the desktop.

Now we can start editing the registry…

1. Press [Windows Key] + R to bring up Run.

2. Type “notepad” (without quotes) into the text box and hit enter.

3. Insert the following text into the document that opens up:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
“dontdisplaylastusername”=dword:1

4. Press Ctrl + S to save the document. As a name, type “loginscreen.reg” and save it on the desktop. (IMPORTANT: enter the name with quotes)

5. Go to your desktop and double click on “loginscreen.reg”. When you are asked if you want to allow the program to make changes, click “Yes”.

6. You can now delete the loginscreen.reg file and enjoy your secure PC!

To change your login screen back to the default setting, repeat the above steps with one small change. The line:

“dontdisplaylastusername”=dword:1

needs to be changed to:

“dontdisplaylastusername”=dword:0

Note: In case you didn’t know, the registry is the part of the computer that stores all its settings. Do not allow programs or files to make changes to the registry unless you know they are trustworthy. It is usually a good idea to make a backup of the registry before editing it. By doing that, you can restore the registry afterwards if anything goes wrong. You can restore the registry by simply double clicking on the exported file.

Facebook Login Notifications

Hey, Facebook users – after a very long time I have again come to my place. My Blog. Was a bit busy settling my second career and with Facebook. But I am back now. Did you know that you can set up India's favourite social networking site to send you an e-mail or even a text message if anyone tries to access your account from a new device?

It’s great for that extra layer of security – and I highly recommend it!

Here’s how:

While logged in to Facebook, click the arrow next to your name, then Account Settings.

Once at the Account Settings control panel click the security category off to the left, then click Edit.

Now simply choose how you’d like to receive a notification when/if your account is accessed from a new/different computer. Click Save Changes when you’re finished!

Word 2007 - Draft View

noreply@blogger.com (Anindya) — Wed, 11 May 2011 15:04:00 +0000

Word 2007 - Draft View

If you’re using either Word 2007 or 2010 and preferred working in the Normal view, then you’re probably wondering what happened to it.

I’m sure you’ve investigated the View tab of the Ribbon and this is what you found:

While on the surface it seems that they’ve done away with the Normal view, the truth is that they just renamed it. Try the Draft view.

Feeling better?

Yeah, I though you might.

Of course the happiness will be short-lived when you save a file in the Draft view and then find that later it opens in the Print Layout view again.

After you’ve changed the view of each document you open to Draft for a few days, you’ll be tired of it and wonder why they created the Draft view if Word wasn’t going to keep the setting when it’s opened again at a later time.

Well we can stop wondering about the whys and still not give up on having things presented to our liking…

Microsoft has included in the program options a place to tell Word whether or not you prefer to allow documents to open in the Draft view.

If you like that view then you’ll want to allow it, and here’s how you can make Word do just that.

Begin in the Office Button / File tab and choose Options.

In the Options dialog box choose the Advanced category on the left

On the right scroll all the way down to the General section.

Locate and select the “Allow opening a document in Draft view” option.

Click OK.

When you next open a file that you saved in Draft view it will still be in Draft view.

Web Browser Navigation

noreply@blogger.com (Anindya) — Mon, 09 May 2011 11:43:00 +0000

Shift+Space Web Browser Navigation

Sounds like a cool new form of space travel, doesn’t it? Unfortunately, (or fortunately, depending on how you look at it) it’s just a trick to make navigating pages in your web browser a little easier.

So, instead of using the Page Up and Page Down keys all the way on the other side of your keyboard, do this:

Press your Space Bar to go a page down.

Press Shift+Space to go a page up.

Quick navigation, without traveling all over the place! Give it a try!
