For those thinking of upgrading to Windows 7 when it is released or just trying out the public Release Candidate (RC) version, you can now use the Windows 7 Upgrade Advisor to scan a computer for any compatibility issues before you install.
The Upgrade Advisor will report known compatibility issues, including software and hardware problems. It will also advise you on how to resolve the issue when possible.
If you are already running Windows Vista, the chances are very high that Windows 7 will run just fine on your system. But it’s worth checking anyway with this free tool from Microsoft.
If you’re one of those that skipped Windows Vista, now’s your chance to find out if that system will run Windows 7. Even if your system reported in the past that it would not support Windows Vista, you should still run the Upgrade Advisor to find out if it will support Windows 7.
I’ve had a few computers that would not allow the Vista install, but are running Windows 7 just fine.
