Windows Taskmanager shows that the System process spikes every couple of seconds to about 30 CPU usage.
I have never noticed this behaviour before and I am pretty sure it did not use to do that :thumbsup:

Using filemon and regmon from Sysinternals I was able to figure out that spoolsv.exe accesses cfgmgr every couple of seconds and also does a bunch of stuff to the registry.

regmon log:

Killing the spoolsv process in taskmanager or stopping the print spooler service stops the spikes.


An HP 3050 Printer/Scanner/fax was installed just recently and I removed all the HP stuff as well as I could (Add/Remove Programs, HP's uninstall link from the start menu). I'm not sure what was left behind though.

Ad-Aware, Spybot S&D and Avira Antivir didn't turn up anything either.

Does anybody have any suggestions on how to stop the spikes with spoolsv running (need to be able to print) or if this is some sort of intended behaviour by HP?

I'd suspect that the HP drivers are still causing the problem because of the remnants left behind after the uninstall. I've seen similar problems on the web within the last few months.

Try googling for "remove HP drivers" or something similar. Then remove the HP drivers as completely as possible from your registry and hard drive to see if that helps!

Be sure to backup before attempting this. If you don't want to try this, then I'd suggest running SFC.EXE /SCANNOW at the Run dialog ( http://www.bleepingcomputer.com/forums/t/43051/how-to-use-sfcexe-to-repair-system-files/ )

If that doesn't work, then I'd suggest a repair install of XP: http://www.michaelstevenstech.com/XPrepairinstall.htm
