I have been looking up that tor may or may not be for windows 10 and I want to use tor for looking around the deep web. several people said that windows 10 has lots of data that can act as spyware.
No, Tor is not safe if you run it on top of Windows 10. Microsoft is a spyware company.
See Microsoft's Software is Malware for more details (e.g Microsoft Surveillance).
Malware means software designed to function in ways that mistreat or harm the user. (This does not include accidental errors.) This page explains how Microsoft software is malware.
