High CPU usage on windows 10

Question

My Windows 10 CPU Usage is always very high, near 100%. Usually it is the Antimalware program.

So, I end the program because I don't need it, but my CPU continues to be at 100%.

How can I fix this?

Update: This is what's taking up my cpu now...

Superfetch Service causes high CPU usage by its function sysmain.dll!PfPdLogEntryProcessHelper:

Now TiWorker.exe (Trusted Instaler Worker) tries to resume to download an update and also extracts and moves the data

Also the Kernel causes high CPU usage by also doing Prefetch Operations like Superfetch

Now the new Memory Compression of Windows 10 causes CPU usage by compressing memory

next the CompatTelRunner.exe scans your PC for installed software, which causes CPU usage. To stop it, disable the scheduled task.

What I see in several processes are DriverVerifier related calls

VerifierExt.sys!IofCallDriver_internal_wrapper

,

ntoskrnl.exe!ViFilterDispatchGeneric

Disable driver Verifier to speedup Windows. It should also lower the side effects in all other processes.

CPU is lower now; antimalware service executable and microsoft compatibility telemetry are the only two problems i see now – suomynonA Mar 19 '17 at 04:59
Defender is always slow. Use a 3rd party anti virus suite. have you disabled the scheduled task? – magicandre1981 Mar 19 '17 at 07:52
There are a lot of them, dont know which one to disable. I reinstalled malwarebytes though, so I think defender will disable on its own. Also what about the microsoft compatibility telemetry? – suomynonA Mar 19 '17 at 16:19
disable all tasks under Microsoft\Windows\Application Experience in taskscheduler – magicandre1981 Mar 19 '17 at 17:22
I did it, should be ok now? – suomynonA Mar 20 '17 at 05:11
yes. it should be better now. Monitor the usage over the next days – magicandre1981 Mar 20 '17 at 16:03
