I have assembled a new PC in the beginning of 2014. I own a legit retail Windows 7 Pro serial number, but it was (and still is) stored inside a TrueCrypt container which lies in an external drive. Then, instead of installing Windows with my legit serial... I felt lazy and used that Daz thing. Now my Windows 10 is "reserved" and, of course, I want to get my free copy; but I'm using the loader, which (as far as I know) is not advisable. Can I use the loader again to deactivate my Windows and then activate it again with my legit serial? Is there any chance to mess the whole thing doing that?
