I received this error code when entering a new, non-original Windows pro key. Before I had Windows 10 Home pre-installed on my laptop, can I somehow get it back or solve the problem? I've already searched the whole internet: /
Have you read this before:

Where did you get the key from?
Yes, I have already read: / got it from MMOGA, who say that this is a problem that has nothing to do with the key…
The keys actually go from there too. 😅 And you don't want a new installation?
Then probably have no other choice 😅
How do I do that? I have a system image on an external hard drive.
