Microsoft yesterday released an updated Windows 7 Upgrade Advisor which provides information regarding your application and device driver compatibility with Windows 7.
Download and run the Windows 7 Upgrade Advisor to see if your PC is ready for Windows 7. It scans your hardware, devices, and installed programs for known compatibility issues, gives you guidance on how to resolve potential issues found, and recommends what to do before you upgrade.
Before you begin: Be sure to plug in and turn on any USB devices or other devices, such as printers, external hard disks, and scanners, that you regularly use with the PC you’re checking.
The Windows 7 Upgrade Advisor scans your PC for potential compatibility issues and lets you know about your Windows 7 upgrade options. Within minutes, you’ll get a report that tells you if your PC meets the system requirements, if any known compatibility issues with your hardware, devices, and installed programs are found, and gives guidance on what to do to before installing Windows 7 on your PC.
