Windows activation after bios update

That is like saying, don't do an oil change or fill up your tank - BIOS updates are made to resolve issues and add functionality. The first question manufacturers will ask when you file a tech ticket is: Are you running the latest bios.

It is like going to JiffyLube getting your oil changed and bring it back to the dealer for a recall and getting refused. I don't know the English word for it, but this ain't right. I have now paid for two licenses because they simply will not understand that I have a LEGALLY obtained license from the Microsoft Store because I build my computer myself. The license is tied to my Microsoft Account, and I never, ever have had this problem. I understand that, by changing the hardware, the license might need to get reactivated.

So, three hundred bucks later, still no activation, time to find other ways.

good luck with that.

For over a month I tried to contact MS support, opening at least 4 tickets. All of them were close after a while, saying the problem was solved. Ridicolous, to say the least.

I just solved myself using the same unofficial tool used by some of their own staff to unlock this issue and finally solve it. I bought a full price, retail license but after this experience I'll never do it again, IF I will ever buy some other license will be through some website selling cheap keys.

Appreciate your replay, however in my case there was no Win11 installation just pure BIOS update on exiting running windows. It seems something is wrong with the system identifying Windows license and hardware and looks like MS is kinda aware of it but not doing anything about it until someone individually cry for help.
Now I don’t really like that kind of approach they should openly admit the flaw in the system and fix it as I’m not buying any NEW license if that happens again after another BIOS update , Just to let this known it happens twice on my Intel Z790 machine no hardware changes but first time when I had update on my Corsair 600LPX M.2SSD but was able to recover license using the "change hardware recently"
Second time when updating BIOS on msi Z790 ACE and after that I couldn’t recover the license
My take about this, something is terribly wrong with MS , Windows hardware detection and licensing system.

I've just had a call back from 3rd line support and even though I showed them this link to this thread he didn't acknowledge there was a problem. He said nothing had been reported.

Anyway he gave me an old fashioned code code and Windows activated ok so I'm sorted. He said it would work if I updated the BIOS again.

So if you want to get yours fixed just persist with the support team, waste 4-5 hours to get to level 3, then another day until they come back and give you a code. Hope that helps.
