If he has Windows 10.

System restore is available under Windows

The question doesn't make sense. You can't reset a laptop. You can reset Windows but back up your important files beforehand so that you can still have them afterwards.

I mean that I want to delete all apps and files and windows (10) are still on

Strangely, everyone here knows what is meant… 🤨

Which is the case.

Yes, I have windows 10 Home
