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.

You can directly install Windows 10 (from version 1511 released on November 2015) using your Windows 7 Product key.

Regarding the activation, as you already migrated your PC to Windows 10, Microsoft stored a numeric signature of your PC Hardware linked to your license.

This means that it will recognize your PC and will re-activate it (it must be the same hardware).
