![]() the CPU Usage comes from te function ntoskrnl.exe!RtlScrubMemory. I've seen this several time but I have no idea what causes it. The only thing I see is that the system runs the Automatic Maintenance. Try to disable this task in the task scheduler. |
Did the trick! Thanks. At first I tried to analyze it myself and found Windows Defender. Then I removed the automatic start of Defender, but it still had 25% after a while idle. Now I removed Automatic maintenance and I no longer have 25% cpu usage when idle. For fun I started maintenance and bam it took 25% (1 core) and it seems to never stop.
![]() I remember seeing a link about ScrubMemory before. It was related to hibernation, so you could reinstall the drivers for your i/o - disk and network. |
Thanks, will keep that in mind if it happens again.
Actually I haven't installed every driver on this computer. I heard about http://www.driverhub.com/ but it seems to be outdated (supporting up to Win7). Is there an alternative?
