Install and use XP mode in Windows7

XPMode
Sometimes all of the compatibility settings in Windows 7 are not enough to make legacy applications run. XP Mode is a free download component for Windows 7 Professional, Ultimate and Enterprise customers that allows you to run legacy apps inside a Windows XP virtual machine running in the background. The end user does not have load and work inside the virtual machines as required in the past. With XP mode they start the application from a shortcut in the Start Menu. It appears like any other window on your desktop and taskbar. The only way you can tell it is running in the XP Virtual Machine in the background is by the XP visual style that surrounds the window.
The only hardware requirement for using XP mode is a computer with a processor that supports hardware-assisted virtualization such as AMD-V, Intel-VT or VIA VT. Microsoft has a helpful tool that will detect if your hardware is compatible called the HAV Detection Tool. On some computers the feature may be turned off in the BIOS, click here for instructions on how to turn it on.
Getting XP mode up and running requires four main steps:
  1. Download and install the XP Mode Components.
  2. Download and install Windows Virtual PC.
  3. Setup the XP Virtual Machine.
  4. Configure your apps in the XP Virtual Machine.
First, visit the XP Mode Web page, select the edition and language of Windows 7 you have and click theWindows XP Mode button to download that component. After the 470 MB XP Mode component is downloaded, install.
Then, return to the XP Mode Web page and click the Windows Virtual PC button and download & install that component. After installing the Virtual PC component you will need to reboot.
After the reboot, click on the Start Menu and navigate through All Programs, Windows Virtual PC and select Windows XP Mode to begin configuring XP Mode.
Click I accept the license terms and click Next.

Next, you will need to specify the password for the local account XPMuser that runs in the XP virtual machine. Type in a password in both boxes and click Next.

XP Mode runs a fully functional Windows XP virtual machine in the background so it must be patched every month as new security updates are released to keep applications running in the VM protected. The best way to accomplish this is by turning on Automatic Updates. Check Help protect my computer by turning on Automatic Updates now and click Next.

Click Start Setup on the following screen.

Setup will now run and configure the Windows XP virtual machine. This will take a few minutes.

When setup is completed the Windows XP virtual machine will be displayed.

At this point install any applications in the XP Virtual Machine like you normally install applications. For a test I installed Office 95.
After setup was completed you should see the programs icons in the Windows 7 Start Menu under All Programs, Windows Virtual PC and finally Windows XP Mode applications.

Just click on one of the shortcuts and the application will load in just like a locally installed app.

If you ever want to service or install more application in the XP Virtual Machine just click on the Start Menu and navigate through All Programs, Windows Virtual PC and select Windows XP Mode. That will start the XP virtual machine in desktop mode.

The Value of Separate User Accounts



The social networking site Facebook has recently been hit with a pretty vicious virus, called “Koobface. It gets on your computer when you click on a link to a video that has supposedly been recommended by one of your friends. This link is to an explanation of how it operates: Koobface

I recently was asked to help a friend whose computer suddenly started behaving strangely, and the bottom line to the story is that her computer had been infected with Koobface. She was able to remove it by running the very good, and free, program Malwarebytes’ Anti-Malware.

So now the question becomes, how did it get there in the first place – as I am sure has happened to many of us, she had recently been visited by grandkids, and they had been playing on the computer. Folks, that’ll do it to you almost every time. Question number two then becomes, what’s the solution to not repeating this again?

The answer is to set up separate user accounts on the computer, with only one account having Administrator privileges, and all others having only limited accounts. A limited account is not able to download and add unwanted things to the computer. Only the administrator can download and install things. I’d suggest anyone who has a computer with multiple users set up separate accounts for each user or group of users depending on the needs of the individuals.

Windows Defender Update Error

Windows Defender Update Error normally has error code 8020000D. To fix this problem follow the below steps. 



Some other program like chkdsk is currently running which locked the disk and so BITS is not able to write to the disk.




If the issue is not being caused by a scheduled check disk, then "something" else is locking the disk or preventing BITS from writing to the download location. That "something" could be security software [antivirus/3rd party firewall/etc], malware, or the Hard Drive may have issues.

If this is Windows Vista, open the Services console.

  • *Right* click Computer either on the Desktop or Start Menu and 
  • choose 'Manage'; 
  • allow the User Prompt; 
  • open Services and Applications; 
  • then Services. 
  • click on Background Intelligent Transfer Service and see if you are able to Start it. 
  • Then try to update Defender again.

Alternatively, you can manually download the latest Defender definition from here, save it, and then manually install it:

World Wide Web

World Wide Web






World wide web is considered as the first component of internet


The World Wide Web (abbreviated as the Web or WWW) is a system of Internet servers that supports hypertext to access several Internet protocols on a single interface. Almost every protocol type available on the Internet is accessible on the Web. This includes e-mail, FTP, Telnet, and Usenet News. In addition to these, the World Wide Web has its own protocol: HyperText Transfer Protocol, or HTTP. These protocols will be explained later in this document.


The World Wide Web provides a single interface for accessing all these protocols. This creates a convenient and user-friendly environment. It is no longer necessary to be conversant in these protocols within separate, command-level environments. The Web gathers together these protocols into a single system. Because of this feature, and because of the Web's ability to work with multimedia and advanced programming languages, the Web is the fastest-growing component of the Internet.


The operation of the Web relies primarily on hypertext as its means of information retrieval. HyperText is a document containing words that connect to other documents. These words are called links and are selectable by the user. A single hypertext document can contain links to many documents. In the context of the Web, words or graphics may serve as links to other documents, images, video, and sound. Links may or may not follow a logical path, as each connection is programmed by the creator of the source document. Overall, the Web contains a complex virtual web of connections among a vast number of documents, graphics, videos, and sounds.


Producing hypertext for the Web is accomplished by creating documents with a language called HyperText Markup Language, or HTML. With HTML, tags are placed within the text to accomplish document formatting, visual features such as font size, italics and bold, and the creation of hypertext links. Graphics and multimedia may also be incorporated into an HTML document. HTML is an evolving language, with new tags being added as each upgrade of the language is developed and released. The World Wide Web Consortium (W3C), led by Web founder Tim Berners-Lee, coordinates the efforts of standardizing HTML. The W3C now calls the language XHTML and considers it to be an application of the XML language standard.


The World Wide Web consists of files, called pages or home pages, containing links to documents and resources throughout the Internet.


The Web provides a vast array of experiences including multimedia presentations, real-time collaboration, interactive pages, radio and television broadcasts, and the automatic "push" of information to a client computer. Programming languages such as Java, JavaScript, Visual Basic, Cold Fusion and XML are extending the capabilities of the Web. A growing amount of information on the Web is served dynamically from content stored in databases. The Web is therefore not a fixed entity, but one that is in a constant state of development and flux.

Creating a short cut for shut down

What is Internet

The Internet is a computer network made up of thousands of networks worldwide. No one knows exactly how many computers are connected to the Internet. It is certain, however, that these number in the millions.




No one is in charge of the Internet. There are organizations which develop technical aspects of this network and set standards for creating applications on it, but no governing body is in control. The Internet backbone, through which Internet traffic flows, is owned by private companies.

All computers on the Internet communicate with one another using the Transmission Control Protocol/Internet Protocol suite, abbreviated to TCP/IP. Computers on the Internet use a client/server architecture. This means that the remote server machine provides files and services to the user's local client machine. Software can be installed on a client computer to take advantage of the latest access technology.
