Various services are running on the PC and handle a lot of activities. One of the key issues is Superfetch, which often consumes system resources. Therefore, some users have been looking for ways to disable Superfetch in Windows 11.

This feature is designed to improve performance and reduce application load times, but can have the opposite effect by slowing down Windows. This usually occurs on lower spec PCs with an HDD (Hard Disk Drive) installed.

What is overfetching?

Formerly known as SysMain, the Superfetch feature is designed to maintain and improve system performance over time, at least that's what the official description reads.

This feature records the mode in which you open apps and preloads them into memory beforehand to save time. For example, if you open a specific program at a specific time every day, Superfetch will automatically load it.

It only takes up the unused portion of memory, and if your computer runs out of it, Superfetch will clear out some loaded apps to free up RAM.

This gives you a basic understanding of its functionality. However, some users have experienced pretty bad performance when Superfetch is enabled and want to disable it in Windows 11. If you are facing the same problem, here are three ways to do it.
