Most users know of the Windows Experience Index Score, it rates your system based on the hardware and displays a score. You can view this either by clicking on Start menu and Games or by opening Control Panel and navigating to Performance Information and tools.

The performance score is calculated by Windows System Assessment Tool (WinSAT) which stores the results in an XML file. By editing this file we can increase the Windows Experience Index Score. Note that we are just going to fake better scores, this is just for show and will not actually help the system perform better !
