Performance Information and Tools aka Windows Experience Index Page Problem in Vista and 7

If you like this article, please share it with your friends and contacts on Google Plus, Facebook and Twitter using following buttons so that they can also enjoy the article:

We all know about new feature “Windows Experience or Performance Index” in Windows Vista and 7. Its a new feature which automatically calculates your system performance index based on the hardware you have.

“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.

It doesn't show the performance details. Even it doesn't 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. Type regedit in RUN dialog box and press Enter. Now 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.

Hello

My Windows Vista "Performance Information and Tools" thing won't finish running. It freezes up my PC, piece by piece, and finally, it reboots itself.

It starts to freeze up while it is "assessing hard drive efficiency" or something and it runs for a-a-a-ages, and then the application minimizes itself and the start bar stops responding, although the sidebar remains active. Then it runs for a-a-a-a-ages and then the screen goes blank but for the mouse cursor. Then screen switches off as though it's in powersave mode (although you've just jiggled the lonely mousepointer) and finally - and eventually - it reboots.

What on earth could be wrong? I've just tried to run it for the first time on this new PC - for the third time - and it won't run through.

Thanks
JOSHUA

^^ It seems a hardware problem. Ask your hardware guy to check the system.

Thats not possible. Its a system key and it'll present in all Windows versions for sure. Make sure you are logged in as Administrator and then try to check the key.
