> Choice doesn't matter to these mega corps
Choice doesn't matter and it's an OK policy to annoy user periodically with options, suggestions, offers, up until it gives up and agrees for something it didn't want in first place but wants to get rid of the annoying notifications or whatever form this harassment takes. The permanent "No, thank you, I'm not interested" doesn't exist in corporate world too - there's only place for "Fine but we will ask you again and again", sadly.
On that note, it was removed, so now the only way I know that works is to do an in-place upgrade via the Windows 10 installation media ('upgrade this pc now') then sign in with a Microsoft account to get your license attached to the MSA, then you can do a full reinstall and keep the license.
