Windows 8 Refresh and Reset Features

2013-08-22T06:26:00.000-07:00

Forgot the Password? Reset, Delete or Remove Windows 7 Password

2013-04-25T05:27:00.000-07:00

We create sometimes very difficult passwords at the same time difficult to remember for us, If you need to reset the password for Windows7 on your computer, because you've forgotten it, let me first assure you that not only is this very possible, it's not even that difficult.

Follow these easy steps to reset your Windows 7 password:

1. Reset your Windows 7 password with your password reset disk.

Which we generally don't create, I put this step here knowing that you probably don't have a password reset disk. However, once you get yourself back in to Windows using the remaining steps, please create one as soon as possible.

2. Download one of the following Windows password reset tools:

ONTP&RE [ Click to Download ]
PC Login Now [ Click to Download ]

Either program will reset your Windows 7 password but ONTP&RE (Offline NT Password & Registry Editor) is my favorite. It's a bit more difficult to use but tends to be more reliable and avoids a data corruption possibility that exists with PC Login Now.

3. Write or Burn the ISO file you downloaded to a disc. Make sure your burn the image properly and don't just burn the file itself to the disc or the Windows 7 password reset program you chose will not work correctly.

4. Boot from the disc you created and let the password reset program start.

Assuming you burned the ISO properly and are booting to the disc properly, you should eventually see the start screen for either Offline NT Password & Registry Editor (here) or PC Login Now (here).

5. Now Reset your Windows 7 password using the instructions provided on screen.

6. Once the Windows 7 password reset is confirmed, remove the disc from the drive and restart your computer.

After your Windows 7 password reset, you can now login to Windows without a password at all. Your Windows 7 password will be blank if asked for one.

If Your Windows 7 Password Reset Attempt Fail?: Try the other program from Step 2 and see Tip #1 at the bottom of the page for help.

7. Now create a new Windows 7 password. That you can get back in to Windows 7, configure a new password right away.

Remember: Having a secure password is very important so please don't keep using Windows 7 without setting one up. Just make sure it's a password you'll remember this time!

Tips:

1. The Windows 7 password reset tools I linked to in Step 2 sometimes don't do the job. If they didn't for you, you could try an actual password recovery program like Ophcrack but honestly, Offline NT Password & Registry Editor and PC Login Now both tend to work better for Windows 7 passwords than Ophcrack.

Thanks & Blessing be on you all!

Can't select a user and unable to assign privileges in MYSQL GUI Administrator

2013-03-12T00:41:00.001-07:00

Problem

Running MySQL Administrator (in the GUI bundle) on MySQL 5.x-community-nt, I cannot use the User Administration: although I do see the list of currently defined users, whichever I select, the page says "No user selected" and all fields are grayed. I tried running the Administrator both as root and myroot (which was Granted all privileges), but it’ as always the same: "No user selected".

Resolution

Step-1

Connect Mysql admin console via command prompt as shown in below screenshot

After connect by entering root password the console is ready to pass query as shown in screenshot.

Step-2

Enter the below query as shown in the screenshot (this query create a new table called user_info)

The above Query in screenshot is given below for your reference.

CREATE TABLE `mysql`.`user_info` ( `User` varchar(16) COLLATE utf8_bin NOT NULL, `Full_name` varchar(60) COLLATE utf8_bin DEFAULT NULL, `Description` varchar(255) COLLATE utf8_bin DEFAULT NULL, `Email` varchar(80) COLLATE utf8_bin DEFAULT NULL, `Contact_information` text COLLATE utf8_bin, `Icon` blob, PRIMARY KEY (`User`), KEY `user_info_Full_name` (`Full_name`)) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin COMMENT='Stores additional user information';

Note: you need to drop the table if already “user_info” is exist by using a below query

DROP TABLE IF EXISTS `mysql`.`user_info`;

Step-3

Now connect Mysql GUI admin console as localhost.

Now check “User Administration” tab you will able to see the users in active editable stage

And also you can able to edit the Schema Privileges for particular DB to particular user.

Introduction

Before we proceed, it would be best to cover some basic user administration topics that will be very useful in later chapters. Adding Users

One of the most important activities in administering a Linux box is the addition of users. Here you'll find some simple examples to provide a foundation for future chapters. It is not intended to be comprehensive, but is a good memory refresher. You can use the command man useradd to get the help pages on adding users with the useradd command or the man usermod to become more familiar with modifying users with the usermod command.

Linux / Unix Commands For Connecting To The Serial Console

2012-09-21T00:37:00.000-07:00

Most embedded Linux / BSD systems such as routers, servers and nas devices comes with console interface (serial port with RS-232). BIOS can use this, and after boot BIOS screen I/O is redirected so that you can use the device. RS-232 is also used for communicating to headless server, where no monitor or keyboard is installed, during boot when operating system is not running yet and therefore no network connection is possible. You need to use a serial cable between your computer and embedded system or server. In this post I will cover five common utilities used for serial communication under Linux / Unix / *BSD and Mac OS X.
