One of my desktops is running Windows 7 (32bit). I am seeing unexpectedly high CPU load for the WmiPrvSE process. Using ProcessExplorer, I can see that it is just one thread that is alternately ranging from 4-15% cpu on an otherwise-idle machine. That thread is entitled ntdll.dll!RtlRegisterThreadWithCsrss. The thrashing is periodic with approximately a five second cycle, with only a brief instant between elevated cpu levels.
Interestingly, when I attempt to invoke csrss.exe manually, I get a dialog box informing me that it can't run in 32 bit mode. Nevertheless, it IS present in the process tree.
So, it appears to me that I have a thread thrashing to interact with something that may or may not be available. What am I missing? Any clues? Thanks in advance!
