In general, if your PC can run Windows Vista, it can run Windows 7. But if you're not running Windows Vista, or are just not sure if your system is ready to run Windows 7, there's a quick way to do a simple check.

Just download, install, and run the Windows 7 Upgrade Advisor. You'll get a report telling you if your PC can run Windows 7, and if there are any known compatibility issues. If the issues can be resolved, you'll get suggestions for next steps. For example, it'll let you know if you need an updated software driver. You'll also get advice on how to upgrade to Windows 7.

Information about your computer will be sent back to Microsoft; however, no information will be used to identify or contact you. For more information, read our privacy statement.

Before you run the Windows 7 Upgrade Advisor, be sure to plug in any USB devices or other devices such as printers, external hard drives, or scanners that are regularly used with the PC you're evaluating.

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.
