Additional System Requirements may be needed to run certain features.
Microsoft is providing a tool called the Windows 7 Upgrade Advisor so customers can determine if their PCs are able to run Windows 7. It is a good idea to download the Windows 7 Upgrade Advisor before upgrading. It will analyze your computer's processor, memory, storage, graphics capabilities, and any other compatibility issues. If possible, it will also provide guidance for resolving issues.
Please note that you should plug in and connect all USB devices, printers, and external hard drives when running the Upgrade Advisor. This will provide the best analysis of your system.
The Windows Experience Index is another indicator of how well your computer will respond to Windows 7. The Windows Experience Index tests your system and rates it with a score of between 1 and 7.9. The higher the score, the better your computer's performance. Some Windows 7 features, like Aero, need a score of at least 3 to run.
In this case, a score of 4.3 should be sufficient to experience most of the new Windows 7 features. If your system scores lower than a 3, you may miss out on some of the digital media and graphics features, including Window's Aero.
