You have some plan to file your files. Just copy them out and you're good to go.
However I find folk really taken aback on installing Windows today. It's a laptop so are you sure they have Windows 7 drivers? Some don't.
Hi all, I purchased a laptop a while ago and it came with windows 10 home. I'd like to upgrade to Windows 10 pro, but instead of paying for an upgrade in the windows store I'd rather use the unused copy of windows 7 ultimate that i already own since you get w10 pro when upgrading from w7 ultimate. All my data is on the C drive so how would I go about backing it up so I can restore it on the new OS? Also would I lose all the drivers and programs for the laptops features such as the webcam, keyboard backlight, etc? I've never really made back ups or restored them with windows so I'm not really sure how it works
