Windows Experience Index - Performance Information and Tools page is completely blank

* Windows Vista
Symptom
When 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?
(Fig 1: ) Rate and improve your computer's performance is completely blank.
Resolution
This 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:
* 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:
* 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 edit
To 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:
* In the right-pane, delete the value named PerfcplEnabled (if found).
* Repeat the same in the following key:
* Exit Registry Editor.
