Windows 10: CPU 100% Usage/Utilization with Nothing Running

In December of last year I upgraded to Windows 10 because of the support for Windows 7 coming to an end. It was around that time I began to notice that my mouse was beginning to stutter and lag. Sometimes I can't even hold right-click for a full 5 seconds without it letting go. My CPU Usage and Utilization is stuck at 100% no matter what.


What I have tried so far:

-Reset Power Options to Default Balanced

-Disabled All Background Apps

-Disabled All Startup Apps

-Ran a full scan of the Windows Defender Scan Found 6 threats and removed them

-Unchecked Number of Processors in the Boot Tab of System Configuration

-Cleaned the dust out of my fans inside the PC

-Uninstalled many unwanted programs and other anti-virus programs that could be eating CPU

-Looked at Task Manager to see what process is eating up all the CPU nothing abnormal

-Updated Drivers

-Temperatures look fairly normal

-Attempted to boot PC in safe mode, CPU Usage normal

-Went into System Configuration, Services, Hide all Microsoft Services and Apply, 100% Usage problem still persists

Forgot to mention: I installed uTorrent a while back, something may have slipped into my computer that I'm unaware of, however, anti-virus doesn't detect it.

CPU utilization >100%

I recently upgraded from Windows 8.1 to 10, and discovered a weird problem when opening task manager where CPU utilization was always at 100%. I did a clean install of Windows 10 to make sure it wasn't application specific, but still the same problem.

This problem is very strange because utilization doesn't seem to be tied to a specific process- it just always seems to add up to 100%. Resource monitor actually shows CPU Usage to be in the million%, which is definitely wrong. No performance degradation,
CPU temps are very normal, and even third-party programs such as Speedfan and CoreTemp are reporting negligible CPU usage (1%-2% idle).

I have tried disabling all startup applications, doing sfc /scannow, viewing reliability history, and restarting multiple times. No luck

 

CPU Usage Always Shows 100%

Hi smac_2718

If Windows 10 is showing your Processor is at 100% and performance is not affected, that and together with the other utility showing this not to be the case, you can assume WIndows is providing an incorrect CPU usage in Task Manager

If your CPU was actually running at 100%, then you would definitely see a performance hit . . .

It is reported a lot on the forums that Windows incorrectly mis-identifies hardware, like processor, RAM . . etc and indeed hardware usage . . .

 

cpu usage at 100%

CPU usage at 100% from start up for no apparently good reason. Service Host appears to be the problem but I cant narrow it down more than that at present.

Any suggestions?

I am using Windows 10 full release version 64 bit.
