“Windows Performance Index” is shown in “System Properties” which can be accessed by right-clicking on “My Computer” icon on Desktop and select “Properties” or from “Control Panel“.
Sometimes when you open Windows Experience / Performance window, you get a blank window showing 2-3 lines as following:
It doesnt show the performance details. Even it doesnt show any kind of help to fix it. So you are left clueless. But don’t worry, here is a solution to fix the issue:
1. Open regedit and goto following keys one by one:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Control Panel\Performance Control Panel
HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Windows\Control Panel\Performance Control Panel
2. In right-side pane, if you see a DWORD value “PerfCplEnabled“. Delete it. Restart your system and now your problem should be fixed.
