svchost.exe takes all cpu power from time to time

hi, i noticed this's happening regularly recently, especially after boot. it generally last for 1-2min. after opening process explorer, i can see it's related to "netsvcs". since it's happening on my computers suddenly, and since i ddin't install any suspicious thing, i wonder if it's not due to windows update..?

It is the latest version of the Windows Update app. Windows Update is run by a svchost process.

Yes, it should update automatically.
Do you already have it installed?

I had the same problem. For me it was a problem with windows updates check reading datastore.edb

Then note RAM usage by datastore.edb during an update check after fixing:
svchost.exe takes all cpu power from time to time-datastore-edb-2.jpg
The fix is not easy.
