Just thought I'd give an update I decided to go with a fresh install of Windows after all. Had no luck try to find another piece of software that is capable of transferring the OS (Windows 10), OS-Files and Personal Files to the NVMe-SSD.
Bit of a shame that I've gotta reinstall some programs buuuuuuuut..... meh, whatever .
Have noticed a couple of odd things since last night so I gotta contact MS about that. Or ask here, but yeah, just thought I'd give an update as mentioned.
