Step 2Running the Windows 7 Upgrade Advisor
Although Microsoft offers upgrade pricing from Windows XP to Windows 7, you will not be able to upgrade your Windows XP installation to Windows 7. You will need to perform a clean install. To make sure you know what software and hardware will need to be updated before making the move to Windows 7, use the Windows 7 Upgrade Advisor. You can run it on systems that currently use Windows XP SP2 or SP3 or Windows Vista.
This program is a small downloadless than 7MB. However, if your system does not have Microsoft .NET Framework 2.0 installed, you will be prompted to install it first.
Before you download and install the advisor, make sure all of the external devices you use with your PC have been plugged in and powered up, such as printers, scanners, multifunction devices, mice, network adapters, external hard disks, and so on. During the system analysis, the upgrade advisor will check all detected hardware to see if driver updates or hardware replacements are necessary.
If you want to use the advisor on more than one computer, click Save when prompted. You can copy the program (Windows7UpgradeAdvisor.msi) to a flash drive or network share for use on other PCs. After you install the program, it checks for updates, then prompts you to click Start Check.
After the program runs, it displays a three-part report (see Figure 2).

The System Requirements section indicates the preparations you need to upgrade to Windows 7 and whether your system passed the requirements. Click See All System Requirements for details (see Figure 3).
