Perfmon is dead. How can I revive it?

[Frank Rizzo]

I start Perfmon and there are no counters available when I try to add a
counter. I finally tracked down a registry key important to Perfmon:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009

and it seems to be missing the Help string value. Meanwhile, the key
forbids me from writing to it, so if I try to create a new data item
there, it comes back with a message box saying: "Cannot create value:
Error writing to the registry.". The permissions are all ok, so I
don't know what is going on.
Am I even going about fixing Perfmon the right way?

I am on Windows XP, service pack 2.
Thanks.
