100% CPU Usage and Antimalware Service Executable

Recommended Posts

Posted · Original PosterOP

In the past few weeks I've noticed that sometimes my PC will slow down, when checking task manager I noticed that some things were casing my CPU to use 100% of its power.

 

The culprits are; Antimalware Service Executable, System interupts and Microsoft Compatability Telemetry. These all cause my cpu to ramp up to 100% for roughly 5 mins before dying down. Windows defender doesn't detect any malware or viruses, I've only downloaded off of legitimate websites with the lock symbol in the top. It never used to happen in the past 2 years of owning. I am on windows 10 Pro version 1909.

 

Does anyone know a solution, is it common or do I have to just wait for an update to fix the problem???

Disable windows defender, and run the windows debloater script from here: https://github.com/Sycnex/Windows10Debloater.

If that doesn't work, install gentoo.
