So if i do a regular install only thing Windows 10 will remove are the widgets Windows 7 and 8 installed themselves not my personal programs or personal files like my music files etc.
Yes, I can't guarantee everything will be there (if you're using windows 7) but Microsoft say so, so I believe them
Though what's worse is the applications that run full screen. Like why would I want calculator full screen? Most likely I'm looking at some numbers in other tabs while putting them in. It was just a fail design aimed at stupid useless tablets. Ruined PC experience in the process.
