High CPU after Win 8.1 update

Question
-
Hi Andre,
I am having the same problem as the others. I have checked for viruses with McAfee and Malwarebytes. Found nothing. I disabled the Application Experience Service in Task Scheduler and Windows Backup. The CPU was still high. Could you take a look at the WTP i created? https://skydrive.live.com/redir?resid=F39F6E8BBE355586!1333&authkey=!AJrOROuWbiK2cs4
Thank you!

You don't have the issue like others. You have a high CPU usgae because you've enabled Driver Verifier. I can see this from calls like ntoskrnl.exe!ViKeTrimWorkerThreadRoutine or ntoskrnl.exe!VerifierExEnterCriticalRegionAndAcquireResourceExclusive.
Disable driver verifier (http://msdn.microsoft.com/en-us/library/windows/hardware/ff556083%28v=vs.85%29.aspx) with
verifier /reset
reboot and the CPU usage should be gone.

I am having similar issues. A process called "System" in the task manager is eating up 6 to 10 % CPU usage. Opening its file location seems to reveal that its "ntoskrnl" application. Driver verifier reset did not seem to do the trick. Any other solutions?Sunday, April 20, 2014 12:13 PM

I did that as soon as the laptop booted for the first time (Its a Y510p and lenovo loads up a lot of crapware). IS 6 to 10 % high for the ntoskrnl or am I being paranoid?Sunday, April 20, 2014 5:06 PM
