Turn off Superfetch on Windows 10.
Turn off Superfetch on Windows 10.
I kept it active but noticed no decline or unusual disk usage. You're free to turn it off if needed, though it remains safe to leave untouched when it doesn't seem to do anything.
Superfetch works well and can boost your PC speed when you use certain files regularly. It keeps often accessed files in your RAM, but they are removed once more memory is needed. Accessing these files is quick, usually only during startup. No concerns here.
This feature doesn't improve performance when turned off. It keeps frequently used files in RAM rather than relying on slower storage devices like SSDs. When you start your computer and run similar programs, SuperFetch already has them ready before you log in. If you play games right after installing Windows, many of your favorite game files will already be stored in memory, making them load faster. With limited RAM, SuperFetch is reduced and stores very little data. If you have plenty of memory, it's inefficient to leave it unused. The system won't cache data while a program is using the disk or when a full-screen app has focus, like a game, but it quietly keeps files in memory for possible reuse if needed later.
