So, I updated my Windows to version 24H2 last night (it forced me to), and when I checked this morning, I noticed the 'activate Windows' watermark. My system isn't recognizing the product key I used when I built my PC back in June. Initially, I had a connection error in the activation settings, but after reconnecting to the internet, I now see the 'no product key detected' error (0xC004F213). I haven't changed any hardware—just the update. Unfortunately, I can't find the original physical copy of my Windows key, and the Device Information tab shows Windows 11 installed yesterday right after the update. I reached out to Windows support, but they couldn't create a ticket because of technical issues, and they haven't called me back despite promising to. I really hope I don't have to buy a new Windows 11 copy just because of this update messing things up. Any advice would be super helpful. Thanks!

Hey! Have you checked if you're logged in with your Microsoft Account? Sometimes that can help restore the activation if it's linked properly. If you haven't, you might want to check Microsoft’s guide on reactivating after hardware changes—it could help clarify some things for you! But since you didn't change any hardware, I'm guessing it should still activate without issues.
I feel your pain! This has happened to several people post-update. A common fix is to go into the activation settings and run the Troubleshooter. It sometimes helps in identifying issues with your product key. If you're prompted about a different PC, give support another call later; they should be able to assist with reactivation without needing your physical key. Good luck!
Thanks for the tip! I’ll definitely try the troubleshoot option first and see if it helps. I appreciate your help!
Yeah, I'm logged in with my MS account. But the link you shared mentions hardware changes, and I really just ran that update. It's frustrating how it just decided to deactivate for no reason!
