I bought a PC from Germany this time last year as a christmas present, it arrived with windows 10 on it in German, got around that eventually (wouldn't allow us to remove German language). Upgraded to Windows 11 last week and it is saying needs to be activated, I have contacted them and they aren't very helpful. The back and forth is painful, so I am hoping somebody here can help me with the easiest method. There is no win 10 key printed anywhere that we can find, not on any manuals, not any stickers or on the PC itself. EDIT - Just to say I tried some vbs script to check key and it gave me one, but it appears as invalid.
