Using this Mentioned method to upgrade Win 7 to 10 will give you the advantage that Win 10 will run even faster then your actual Win 7 setup. I upgraded my 8 year old machine and it runs twice as fast as with win 7 . there was no need for any new drivers all got managed with the Microsoft upgrade tool on a stick.

as a security measure I just mirrored my Win 7 on a other empty drive using Paragon if I wanted to plug in win 7 again.
