Usually my system performs fine. However, periodically, there are temporary performance drops. Basically the Task Manager shows 100% HDD usage and the culprits invariably turn out to be system related processes like:

  • MsMpEng.exe Antimalware Service Executable
  • AppXSvc AppX Deployment Service (AppXSVC)
  • svchost.exe Service Host: Superfetch
  • ntoskrnl.exe System
  • CompatTelRunner.exe Microsoft Compatibility Telemetry
  • And others.

I don't what is Windows doing - scanning my computer for threats with Windows Defender, downloading and installing updates, defragging HDD - but whatever it is I hope its not going kill my HDD anytime soon and can Windows please do all of this while I'm afk and certainly not when I play League of Legends!

I can't help but notice Linux Mint doesn't experience these periodical performance drops. This persists for a few years already, I'm frankly fed up with this.

Can anything be done to alleviate this issue?

In all of my experience, majority of the time SuperFetch is the culprit for hard drive slow downs.

Here is a guide on how to disable SuperFetch.

You shouldnt have any issues come up after disabling it.

Here is a brief overview of Superfetch and how it can impact performance if you're using an HDD instead of an SSD:

There is also a section showing how to disable it as a service if it's causing trouble. I don't know if this is the source of your issue, but I hope it helps, nonetheless.

Usually, when I've had slowness issues, it's a combination of Superfetch continuing to run at the same time an A/V was trying to access the disk (Sophos, Avast, ESET, all of these). When they would start running together, you'd see 100% Disk usage, between 20 - 30% CPU and over 50% Memory usage
