To see if your PC is ready for Windows 7, download the free Windows 7 Upgrade Advisor. It scans your PC for potential issues with your hardware, devices, and installed programs, and recommends what to do before you upgrade. (If you’re already running Windows 7, you can add premium features online with a Windows 7 upgrade.)
The Windows 7 Upgrade Advisor checks for compatibility issues.
If your PC can run Windows Vista, it can probably run Windows 7, but it’s still a good idea to download and run the Windows 7 Upgrade Advisor before you begin the upgrade process.
