Symptoms

Assume that you try to open Games Explorer on a computer that is running Windows 7. However, it takes a long time for Games Explorer to be displayed. This issue occurs if the value of the DevicePath registry entry under the following registry subkey includes locations that contain many device drivers:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

Cause

This issue occurs because of an error in the Windows System Assessment Tool (WinSAT). When you open Games Explorer, WinSAT displays the performance rating score of the computer in the Games Explorer window. WinSAT calculates the performance rating score by enumerating system devices. System devices are specified in the DevicePath entry. Therefore, if the value of the DevicePath entry includes locations that contain many device drivers, WinSAT takes a long time to calculate the performance rating score.
