You still have not mentioned the application you are using.
You can use the OEM Product Key again, as long as it is a valid key and you have not changed motherboards.
If I had a valid Product Key, I'd just do a clean install, rather than move/clone/image.
A valid Product Key is typically found on a Certificate Of Authenticity sticker on the PC and will have 25 characters in 5 groups separated by a hyphen, like this:
xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
You can even call Microsoft and have them tell you if it is a valid Product Key.
