I have running Win 10 Home edition and by mistake got Education N product key from uni. Is it possible now to upgrade from Home to Education N? I get error 0xc004f050 if I try to use Education N product key.
Not really. Due to some misunderstanding got N one, but had a choice for non-N too and now can not "exchange". Probably. Enforcing EU laws on MS or Google or FB is a good practice.
The enforcement is about a stupid thing, in the past it was also about msie being pre-installed, but N editions only cause future problems. So, if you have a non N key, disconnect from the internet and insert the key.
