How can i clean out a laptop without reformatting?

I'm selling a laptop to a friend, and i want a clean windows 10 on it but i don't have the time to reinstall windows.. are there any software like ccleaner that i can use to clean out my personal data and stuff?

Even if there was such a software, it would take much more time than simply reinstalling Windows.
Windows 10 has a feature which lets you do a clean install.



P.S. If your friend works in IT he might try to recover deleted files. But there is a safer deletion option when reinstalling but the processmight take 12 or more hours.

If you have Windows 8, you can go back to the factory
Just keep up with youtube on reset windows 8

you can verywell delete the .profile folder <user profile> to start it fresh but be cautious to take your backup
