I was going to use a laptop for dj work, and of course stupid updates cause music to stutter.
Here’s a post on stopping it. Best to read the whole thing but here’s the crux of the matter:
-
Press [Windows] + [R] and type services.msc.
-
Look for the “Windows module installer” and open the Settings.
-
Switch the start type to manual. Repeat this step for the Windows Update service.
-
Open the Control Panel and click on Windows Update.
-
On the left side you can see the option Change Settings. Switch it to “Check for updates but let me choose whether to download and install them”.
-
Reboot your computer.
With this steps you set the Windows update process to manual, which means the high CPU usage by the Windows Modules Installer in Windows 10 respectively Windows 8.1 should be fixed. At least it no longer stars in the background. You set the Windows Update to manual, so you have to start the update regularly by yourself.
