Missing Perfmon 'Processor' counter in Server 2003 VM after 4.1 U3 Tools Upgrade

Has anyone else seen the issue with the standard Windows perfmon.exe 'Processor' counter being missing after upgrading the VM tools on a Server 2003 system to 4.1 U3?  (screen shot below)

We now have about 5 reported servers that are missing this counter.  The new 'VM Processor' (and 'VM Memory') counters are present, but the standard Windows counter is missing.

I'm working through http://support.microsoft.com/kb/300956 now on one of the systems to attempt to recover/recreate the counter, but if anyone has a faster method and/or ideas of why the counter went missing, it would be appreciated.

Thanks for your time.

It appears this issue is only related to Server 2003 64bit.  The PerfOS registry setting has a subkey under 'Performance' named 'Disable Performance Counters'.  The 'Disable Performance Counters' should be set to 0 (zero) to enable the 64bit counters.

Full details in http://support.microsoft.com/kb/2554336.

I'm still unclear how this subkey was added since it doesn't appear it should even exist (at least it doesn't in any other 'Perfxxx' registry entry keys.

Hopefully this helps someone else having the same problem.
