    • Right-click on both the "Debug" and "Trace" log options within this folder, and select "Enable Log" for both (the "Operational" log should already be enabled and logging generic events)

    Reboot, and after the next time you see high activity in wmiprvse.exe, see if there's any activity in these two newly-enabled logs.

    TZres.dll file created over and over again solved

    Long story short, I've spent a day investigating the spikes my cpu made at idle (between 4% and 16%, the culprit was tzres.dll accesed by WMI trying to create a file over and over again.

    Probable causes I found browsing the internet wirth their solution:

    1) Windows Resources Management software - not installed on my system, an official patch exist if you're affected

    2) Malware (opencandy, conduit etc...) - use an anti malware program like adwcleaner or hitman pro

    3) Temporary solution with no culprit found - restart the Windows Management Instrumentation service, the bad behaviour will come back after reboot

    None of these solutions satisfying me, I remembered Antivirus software use the time of your computer in their procedures to weed out malicious programs. TZres.dll dealing with timezones, I decided to investigate and VOILA, the culprit on my system is AVAST ANTIVIRUS.

    Uninstalled and the spikes were gone, my cpu stays at about 2 to 3% at about 600 Mhz, perfect for my little atom tablet!

    Hope this helps

    PS: Installed Panda cloud antivirus and the spikes did not return! It is also supposed to be light on resources and quite effective if you believe the last AV-comparatives test AV-Comparatives Real-World Protection Test » AV-Comparatives

    Sysinternals Process Explorer is an excellent utility that can help you track down problem processes and malware. Learning how to use it is key:

    SysInternals Pro: Understanding Process Explorer

    Process monitor can be useful also, but there is much more info to wade through, as it monitors registry changes, which can eat up system resources very quickly if you let it run too long. It's general use is to fire it up and start capturing when the problem process starts, stop the capture when you think you've caught it and examine the traces.
