The above command will completely flush the DNS, deleting any incorrect entries too. You can also use the command ipconfig /displaydns to view the DNS resolver cache.

Turning Off DNS Caching under Microsoft Windows

If you experience frequent issues with DNS caching under Microsoft Windows, you can disable client-side DNS caching with either of these two commands:

net stop dnscache
sc servername stop dnscache

This will disable DNS caching until the next reboot. To make the change permanent, use the Service Controller tool or the Services tool to set the DNS Client service startup type to Disabled. You can permanently disable DNS Client by following the below steps:

• Goto Start and click on Run.
• Type Services.msc in the Run command box.
• A window listing all the services will popup. Search for a service called DNS Client.
• Double click on the listed DNS Client service and click Stop. Similarly, you can restart it by clicking Start.

Tuning DNS Caching under Microsoft Windows

You can modify the behavior of the Microsoft Windows DNS caching algorithm by setting two registry entries in the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesDnscacheParameters registry key.

The MaxCacheTtl represents the maximum time that the results of a DNS lookup will be cached. The default value is 86,400 seconds. If you set this value to 1, DNS entries will only be cashed for a single second.

MaxNegativeCacheTtl represents the maximim time that the results of a failed DNS lookup will be cached. The default value is 900 seconds. If you set this value to 0, failed DNS lookups will not be cached.

As a no-cost service for genuine Windows PCs, Microsoft Security Essentials offers you comprehensive, state-of-the-art protection against malicious threats such as viruses, Trojans, spyware, and other malware. Microsoft Security Essentials:

Delivers quality protection backed by industry standards and ongoing research into software threats.

Built on the Microsoft industry-certified antimalware protection platform, Microsoft Security Essentials takes advantage of the same core antimalware technology that fuels the rest of the security products from Microsoft, including Microsoft Forefront, the Malicious Software Removal Tool, and Windows Defender, and has received the VB100 award from Virus Bulletin Ltd., Checkmark Certification from West Coast Labs, and certification from the ICSA Labs. Microsoft Security Essentials is backed by the Microsoft Malware Protection Center (MMPC),

Makes it easy to stay protected after a simple download.

It’s as easy as clicking a download button to get Microsoft Security Essentials. Your system downloads Microsoft Security Essentials in the language you need and installs* with a few simple clicks.

Once you have installed Microsoft Security Essentials your software updates automatically, making it easy to sit back and relax.

Microsoft Security Essentials uses the Microsoft Update service to ensure the signatures, antimalware engine, and application are automatically updated. New malware signatures are downloaded once per day with the new signatures accessed in near real time through the Dynamic Signature Service. As the threat landscape changes and new malware emerges, malware engine upgrades and new application features are also delivered to you automatically through the Microsoft Update service.

Is simple to understand and easy to use.

Microsoft Security Essentials runs quietly and efficiently in the background so that you are free to use your PC the way you want. The software uses the popular green-yellow-red color coding to designate the security status of your PC, and a color-coded icon in the taskbar tells you at a glance if your attention is required. It’s simple – when you’re green, you’re good. However, if a yellow or red icon is present, you can take the required action directly from the system tray icon without having to enter the application.

When user intervention is required, clear status and recommended actions are presented to you on the home page and through application alerts, which are designed to minimize interruption. In addition, you can take immediate action directly from an alert.

Doesn’t get in the way of PC performance.

Microsoft Security Essentials doesn’t carry the weight of suite products and has a much smaller download size. Scans and updates are scheduled to run when the PC is idle and use a low-priority thread. CPU throttling ensures that no more than 50 percent of the CPU is utilized by Microsoft Security Essentials activity, so that your system continues to perform those tasks you are likely to be performing, such as opening files or browser windows, saving files, and using cut, copy, and paste. Microsoft Security Essentials uses smart caching and active memory swapping so signatures that are not in use are not taking up space, thus limiting the amount of memory used even as the volume of known malware continues to increase. This makes Microsoft Security Essentials friendlier toward older PCs, as well as today’s smaller, less powerful form factors such as netbooks.

We are focused on ongoing Microsoft Security Essentials performance improvements as well. Telemetry on files that are slow to scan is sent to Microsoft for analysis and resolution, and routine engine updates can incorporate advancements for improved scanning speed, remove unneeded signatures, and reduce memory usage.

Runs quietly in the background.

Microsoft does not push offers or display information-only pop-up windows or update status notifications. Microsoft Security Essentials simply runs quietly in the background. You will be alerted only if and when there are specific actions that need to be taken. When you are not present or are too busy to take the recommended action, Microsoft Security Essentials can take the default action on your behalf; you can launch the application at a later time to review and adjust actions taken if desired.

Clearly, the trend is toward remote and mobile computing, and it’s important for an operating system to provide the tools necessary to remain connected and productive from anywhere. Microsoft is incorporating a variety of new networking features in Windows 7 that simplify connectivity and help users access network resources no matter where they are connecting from. Here we’ll take a closer look at some of the innovative networking features to be found in Windows 7 (we may get a little bit technical at times).

HomeGroup

Let’s start with an enhancement aimed primarily at home users and home businesses: With Windows 7, Microsoft introduces the concept of HomeGroup. The HomeGroup feature serves two primary purposes: (1) to make sharing files and resources between computers on a home network easier, and (2) to protect shared files and resources from guests or wireless-network intruders.

Many homes have multiple computers, and users want to be able to share music and pictures, or network all of the computers so as to print to a single printer. This type of local area networking has been possible in Windows for years, but it has often been easier said than done, leading to many hours of user frustration.

Open HomeGroup from the Control Panel. Click on Create a HomeGroup to begin the process. You can determine the types of files or content that you want to share with the HomeGroup by checking or unchecking the appropriate boxes.

After you click Next to create the HomeGroup, Windows 7 will automatically generate a password that other users will need in order to join the HomeGroup and share the resources. Windows 7 Starter and Windows 7 Home Basic versions cannot create a HomeGroup, but computers running any version of Windows 7 can join a HomeGroup. One significant drawback to the HomeGroup concept is that it works only with Windows 7, so any Windows XP or Windows Vista systems in the home will not be able to participate.

Using a HomeGroup simplifies the process of sharing files, folders, and other network resources with trusted computers on your home network. At the same time, it enables you to allow visiting guests to connect to your wireless network for Internet access without also granting them access to the shared content and resources. It also prevents any unauthorized rogue wireless connections from gaining access to shared resources.

You just just finished installing a fresh copy of Windows 7 on your computer and have it set up to your liking. One of the first things you should do now is create an image of the disc so in the event of a crash you will be able to restore it to its current state. An image is an exact copy of everything on the drive and will restore it back to its current state. It’s probably best to create an image when everything is clean and organized on your system. This will make the image file smaller and allows you to restore the system with a smooth running set up.

Creating an Image in Windows 7

Click on Start go to Getting Started and then select Back up your files.

Next click on the Create a system image hyperlink.

Decide where you want to save the image. You can choose an external drive, burn to multiple DVD’s, or store it on a network location.

You can include other drives if you want as well but remember that will add to the size of the final image.

At the confirmation screen notice the amount of space the image may take. If something doesn’t look right you can still go back from this point and make adjustments.

A progress meter is displayed while the images is created and backed up. In this example a disk of about 15GB in size took under 20 minutes backed up to an external drive. Times will vary depending on your system and where you’re backing it up to.

After the process is complete you get the option to create a system repair disc which you should do and make sure to save it in a secure location.

When it comes time to restore the image, you will be able to use the System Recovery Options to get the system back.

• %SystemRoot%Driver Cachei386drivers.cab
• %SystemRoot%Driver Cachei386service_pack.cab
• .inf files under %windir%inf
• .sys files under%SystemRoot%System32Drivers
• Support DLLs under %SystemRoot%System32
• Third Party co-installers in various locations.

DriverStore is a new and a central location in Windows Vista and Windows 7 where all the driver files will be stored, before they are copied to theirfinal destination during the device driver installation.

For example, the driver package developed by Microsoft that contains the core mouse
support files is present in the following folder:

C:WindowsSystem32DriverStoreFileRepositorymsmouse.inf_amd64_neutral_6f653f6716c1448c

Keeping the drivers in a central store allows for a much faster device installation and a more reliable driver rollback.

Back up your files

To help ensure that you don’t lose your files, you should back them up regularly. You can set up automatic backups or manually back up your files at any time.
