Nothing that directly answers your question: running the same code
 on my Win2K machine gives the same result, but I have close to
 no knowledge on Win32 performance counters.

However, can I can offer the following ray of hope? The following
 code works for me:

<code>
import wmi
import time

c = wmi.WMI ()
while 1:
  for p in c.Win32_Processor ():
    print "%s running at %d%% load" % (p.Name, p.LoadPercentage)
    time.sleep (5)

</code>

Obviously, I don't know if what else you're doing relies specifically
 on the Performance Counters, in which case this isn't such a useful
 example. Some of them are available via WMI, but I don't know if 
 they all are.
