Windows VistaSymptomWhen I right-click
Computer and choose
Properties, I can see the Windows Experience Index on my Control Panel\System applet. But when I click on the
Windows Experience Index link, I go to the Performance Information and Tools page, but the Windows Experience Index details are missing completely, so I can't view or update the scores. How can I get it back?

Rate and improve your computer's performance is completely blank.
ResolutionThis happens if a policy is set which removes access to the Performance Information and Tools page. If you're the administrator of the system, follow one of these methods below to relax this restriction:
Method 1: Using the Group Policy Editor * Click Start, type
GPEDIT.MSC and press ENTER. This opens the Group Policy Editor.
* Navigate to the following branch:
CODE
Computer Configuration | Administrative Templates | System | Performance Control Panel
* Double-click
Turn off access to the performance center core section * Set it to
Not configured If it's already set to Not Configured, set it to Enabled and click Apply. Then revert back the setting to Not Configured. This resets the registry based policy if set already.
* Repeat the steps in this branch as well:
CODE
User Configuration | Administrative Templates | System | Performance Control Panel
* Exit the Group Policy Editor.
Note: Group Policy Editor is not available in certain versions of Windows Vista. If your version of Windows Vista does not have the Group Policy Editor, follow the registry editing method instead, which is listed below.
Method 2: Registry editTo automate the following steps, download
perfcpl_enable.reg file attached at the end of this article. Download the REG file and save to Desktop. Right-click on the file and choose
Merge.
* Click Start, type
regedit.exe and press ENTER
* Navigate to the following location:
CODE
HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows \ Control Panel \ Performance Control Panel
* In the right-pane, delete the value named PerfcplEnabled (if found).
* Repeat the same in the following key:
CODE
HKEY_CURRENT_USER \ SOFTWARE \ Policies \ Microsoft \ Windows \ Control Panel \ Performance Control Panel
* Exit Registry Editor.
Attachmentsperfcpl_enable.reg I had the problem, downloaded the perfcpl_enable.reg and merge , it worked.
