HOW TO: Disable Superfetch in Windows 10

Superfetch is another process in Windows with roots as far back as a service called Prefetch in Windows XP, which was replaced by Superfetch in Windows Vista and has been on every consumer version of Windows since. It is designed to improve performance by pre-loading applications that you use frequently into memory so loading it seems snappier. However, Superfetch can sometimes bring mechanical hard drives to their knees for a time after logging in.

Even if its not causing too heavy of a load on my hard drive, my opinion is that any performance increase isn’t worth the initial drag on my systems at login so I generally disable it as part of the initial Windows setup on my machines. I’ve disabled it on all of my personal Windows machines, as well as several client devices with complaints of being slow, and have not experienced any negative side effects. If you want to see if it’ll help boost your PC’s performance, keep reading! Continue reading “HOW TO: Disable Superfetch in Windows 10”

HOW TO: Disable Windows Compatibility Telemetry in Windows 10

Windows Compatibility Telemetry is frequently the culprit behind a slow Windows 10 experience as it attacks your hard drive and bogs everything down. Here’s a quick fix to disable WCT permanently*.

Create a restore point!

wincomtel

  1. Open Task Scheduler (in Start, search “Task Scheduler”)
  2. In the left pane, navigate to:
    • Task Scheduler Library
      • Microsoft
        • Windows
          • Application Experience
  3. Right-click on “Microsoft Compatibility Appraiser”
  4. Left-click on “Disable”

That’s it! Simple! While I’ve done this on all of my personal systems, and several client systems, without trouble, if you suddenly start encountering problems after making this change, you can easily re-enable WCT following the same steps.

* I verified that this fix works as of Windows 10 1803 on 2018-11-13, however Microsoft is constantly “improving” Windows 10 so this fix may not work after future updates. If you encounter any issues with this fix, see any errors, inaccuracies, or omissions in the post, and/or have any other feedback, leave a comment or tweet me @AwkwardPrimate! Thanks!
