Resolution
If you are seeing these types of errors in the cdm log here is the solution:
Verify on local Windows XP/2000/2003/2008 etc machine that performance counters are intact and visible using 'perfmon' tool on the local system e.g., for Processor.
If the perfmon counters are corrupted on your machine you’ll see numbers like 1151, 1112, 1167 etc. instead of counters/strings.
Also please check out this Microsoft KB article:
http://support.microsoft.com/kb/300956
If your counters are corrupted for instance: you can try issuing this command as administrator:
lodctr /R
Then recheck the counters to make sure they are repaired.
If the counters are successfully repaired, you will still need to reboot after the rebuild.
Also via regedit, take note of:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PerfOS\Performance
In this key, there could be a Disable Performance Counters value that is set to 1. You may have to reset that value to 0, and then Deactivate and Activate the cdm probe.
Also note that by default, some counters are not enabled on Windows machines so they have to be manually enabled. For more info see:

It means that windows standard API RegQueryValueEx is failing to get registry handle for key HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Perflib\009

go to registry editor using regedit command and check the HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Perflib\009
