Windows 10: Is Superfetch really safe to stop?

Please let us know how it went.

 

It is safe but I bet you a (imaginary) dollar it will not be beneficial. Most likely if you notice a difference at all disabling it will make things (marginally) worse.

It was after all designed to preload things you use often to improve performance where HDD was the bottleneck in the system. It certainly wasn't designed to deliberately make Windows go slower - that would be silly.

Anyway, when you enable or disable it, run it for a few days each way and see which works better for you. When running it needs to learn your typical patterns - whether you tend to boot up and open your email and Word for example or instead open Twitter and VLC; what time of day you do it (email in the morning VLC in the evening) and so on....

 

I guess it didn't go very well. I disabled Superfetch along with a bunch of other services and didn't notice any difference. Then I restarted Superfetch and didn't notice any improvement. My unreliable internet connection doesn't make it easy to tell if something speeds up or slows down my computer though. I guess it's safe to say that there hasn't been any big difference either way.

 

Then, if you really don't see any noticeable benefit, no reason to not leave the Windows defaults as is. Down the road if something goes boop!, you may not be able to tell if it's your changes, or something new.
