As discussed some windows services Running background cause unnecessary system resource usage. Disabling these services, Specially Superfetch, Disable Background Intelligent Transfer Service (BITS), windows search and windows update can help to fix this 100% disk usage problem.

About These services :

Superfetch Service: Superfetch is one of those Windows services that will always have the potential of delivering a better sweet user experience. The premise behind Superfetch is that Windows will learn from your usage habits and “guess” which applications/services you’re most likely to use next. Based on this prediction, the OS will cache those apps and programs to the RAM, so they’ll load faster. This is a fantastic concept, but unless you’re a robot that’s programmed to follow a particular routine, Superfetch’s predictions are bound to miss from time to time. And because the service is busy pulling all those predicted app files and data from your hard disk, you get the 100% Disk Usage error.

BITS: BITS is yet another Windows 10 service that’s supposed to be helpful but can turn out to be quite the opposite. The idea behind BITS is that when your computer is sitting idle, the bandwidth can be used for Windows Update, Windows Defender and the like. While it usually works just fine on newer machines, older hardware can actually suffer while BITS tries to decipher when the computer is actually idle.

While Superfetch caches data to RAM based on intelligent guessing, Prefetch works when you launch those applications.

However, Prefetch isn’t your standard Windows service, we need Tweak windows registry to Disable prefetch Service.

Press Win + R, Type regedit and hit enter key. Here on the registry editor first backup registry database then navigate to following :

HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\SESSION MANAGER\MEMORY MANAGEMENT\PREFETCHPARAMETERS

In the right side panel, you’ll see an entry for EnablePrefetcher. Double-click it and change the DWORD value from 3 (default) to 0 to completely disable the service. You may also put in 1 as the DWORD value, which will keep Prefetcher partially enabled but disabled for boot files. click ok and close the windows registry editor.
