If you are comfortable using registry editor you can find these 2 keys:

HKLM\Software\Policies\Microsoft\Windows\Control Panel\Performance Control
Panel!PerfCplEnabled
HKCU\Software\Policies\Microsoft\Windows\Control Panel\Performance Control
Panel!PerfCplEnabled

The data should be set to "1" for the performance page to be enabled.
