I recently upgraded from windows 7 Ultimate to windows 10 Pro. My question is- How to re-install windows 10 pro after wiping the HDD without losing my license? Where are the activation files to take backup?
Note: I have already taken backup of my previous windows 7 activation files using this method. Should I try the same exact method for windows 10 activation files? Will it work?
Note 2: I have the product key from previous windows.
