Windows 10 allocates some system resources to random tasks and services that you probably have no need for or interest in. Unfortunately, most of these tasks, services, and processes can’t be removed or disabled, so you are stuck with the resource drain. That being said, one service that can be disabled is Superfetch, so follow along as we show you how to turn it off.
How to Fit 100% Disk Usage on Windows 10.
Most of the processes that run in the background on Windows 10 are necessary for everyday use and help with the overall performance of the operating system. With the exception of Cortana (popular opinion). Superfetch is one of these processes that ‘should’ make life easier and most importantly faster, that being said, this isn’t always the case.
A lot of the time Superfetch can be counter-productive and slow things down, rather than speed them up. Superfetches basic function is to make note of the programs, apps, and tasks that are used most frequently and keep them at the ready for quick access.
Although this is the case for most users, there are times when Superfetch does the opposite and keeps disks running in overdrive and ram full of unneeded data. If you suspect that Superfetch is causing you issues, it's relatively easy to disable and re-enable, so follow along as this guide takes you through the process of doing both.
How Do You Disable SuperFetch on Windows 10?

How to Disable SuperFetch From the Windows 10 Registry Editor.
If you would rather disable SuperFetch using the registry editor, you’ll need to do the following. Open the Windows Run tool by pressing Windows Key + R, then type regedit and press Enter. When the registry tool opens, copy and paste the following line into the address bar to jump to the location. (Alternatively, you can navigate there manually)
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters

After changing the value to 0, you can exit the registry editor and restart your system. After a restart, Superfetch will be disabled.
