The backbone for the Windows Experience Index scores comes from the same new technology built into Windows Vista that enables it to scale, called Windows System Assessment Tools (Win SAT).
These tools run tests that discover and assess the performance characteristics and capabilities of a PC.
More specifically, the Windows Experience Index is a tool to measure your computer’s performance, based on its hardware and software configuration.

I have followed the procedure in here SFC / SCANNOW Command - System File Checker with the sfc scannow command. Hi all, Tried searching the forums but could not seem to find anyone with the same kind of problem I've ran in to.Because performance is important to delivering the advanced scenarios and applications being developed today, Windows Vista also includes a new system designed to help average users simplify those performance considerations as part of the PC, hardware upgrade and software purchasing process called the Windows Experience Index (formerly named Windows System Performance Rating or Win SPR).The Windows Experience Index provides the user or administrator with a high-level assessment of a given machine's performance capabilities expressed as a number 1-5.The WEI includes five subscores: processor, memory, 2D graphics, 3D graphics, and disk; the basescore is equal to the lowest of the subscores and is not an average of the subscores.The WEI enables users to match their computer hardware performance with the performance requirements of software. Here's mine: I never ran Vista's WEI, so I'm also wondering how W7 RC1 WEIs compare to their Vista counterparts on the same machine.
