WMI Provider Host taking up half of CPU?

Question

Recently, I have had something called WMI Provider Host in my Task Manager that is taking up about half of my cpu. How do I fix this? Thanks!

does the activity go away after a reboot and come back later, or does it start as soon as the PC boots? — Frank Thomas, Jun 24 '13 at 16:46
Ok, I rebooted but it is not appearing but my user says its taking more pc than it is — colin, Jun 24 '13 at 16:52
its like saying its 20% on my user but cpu says i, taking like 90 — colin, Jun 24 '13 at 16:53
follow the steps here: http://pastebin.com/v9Ct1RFr and give me the WMI xperf logging file. — magicandre1981, Jun 24 '13 at 17:19
Please run the xperf commands. this will tell me which process does WMI calls. But I need the trace. — magicandre1981, Jun 24 '13 at 17:40

Try to enable WMI activity log in event log, (enable "show analytic and Debug log" in view option of event viewer), check which WMI query is running in Microsoft-Windows-WMI-Activity/Operational and trace log. Or you can consider to rebuild wmi repository: https://blogs.technet.microsoft.com/askperf/2009/04/13/wmi-rebuilding-the-wmi-repository/

Could you expand on how to rebuild the WMI repository? – Burgi Jun 29 '16 at 07:32
The link I provided has a script to do that, but you can also manually rebuild it with 3 steps. 1: disable winmgmt service, 2. rename (backup) %windir%\system32\wbem folder 3. start winmgmt service. – Kevin Tu Jun 30 '16 at 02:57

More like *if* ms changes the link, that part of your answer becomes useless. So its always nice to have those sort of things in your answer, quoted or paraphrased appropriately. – Journeyman Geek Jun 30 '16 at 07:45
