Part of the problem with the release of Windows Vista was that many apps (particularly corporate applications) simply did not work. In an effort to encourage the adoption of Windows 7, Microsoft developed XP Mode. XP Mode allows applications that run under Windows XP to run alongside Windows 7 applications. Unfortunately, this feature is only provided for the Professional, Enterprise and Ultimate Editions of Windows 7.
XP Mode can also be used to run different versions of the same application side by side. As a web developer this allows me to run IE8 (running in Windows 7) and IE6/IE7 (running using XP Mode) side by side for testing web site compatibility.
Lets see how to install and get started with XP Mode in Windows 7. i have divided to four parts that will be easy to understand step by step tutorials.
Part One: Downloading XP Mode and Virtual PC
Step 1. Navigate to the Windows XP Mode and Virtual PC download page, and select your edition of Windows 7 and desired language for installation. If you’re not sure what edition of Windows 7 you are running follow our guide to find out.
Step 2. Download XP Mode
Step 3. You may be prompted to validate your copy of Windows. Click Continue to proceed.
Step 4. Save the file to your computer and run it once the download is complete.
Step 5. Once the Windows update installation has finished, click Continue.
Wait for the validation process to complete.
If the validation was successful, then you should get a message similar to the following. If you get an unsuccessful message, then your copy of Windows may not be genuine and you will not be able to proceed.
Step 6. You should now be able to download Window XP Mode.
Step 7. Download Windows Virtual PC.
Step 8. Install the update to XP mode, if you are not on Windows 7 SP1 or later.

Wait for it to complete.
Restart if prompted to do so.
Part Three: Setting Up and Configuring XP Mode

Step 6. When the installation is complete XP Mode will be running within Windows Virtual PC.
Part Four: Installing Applications in XP Mode

Step 5. The application should now be running alongside your other Windows 7 apps.
Step 6. If you want to run an application that was installed with Windows XP such as IE6, open XP Mode again from the start menu.
Step 7. Create a shortcut to IE6 in the C:\Documents and Settings\All Users\Start Menu\Programs folder.
