Windows 11 OEM licence deactivated after 24h2 update

I am having the same issue after updating to 24H2. My Windows 11 Pro (23H2) is activated *not* with a digital license, despite being able to see the device as one of my devices in my online Microsoft account.

I updated to 24H2 tonight, and got the error that Windows is no longer activated. Went through the troubleshooter (didn't work).

I requested a callback, and surprisingly someone called after midnight Eastern! The agent said to rollback to 23H2 and turn off updates for the "next few days" since it appears they are aware of the problem.

No further information was given, but he said if you experience this, roll back to the prior version for now while their engineers work on the problem.

It appears there is some sort of glitch they're aware of, if the support agents are telling you to rollback for now and to pause the updates.

I went and dug out Microsof support's previous reply from October, this was their advice to fix if you want to try but to me it is a really, really poor solution to drop on customers. I have not tried it yet as struggling for time.

Just located my product key for Windows 11 Pro and tried to re-enter the key.

However, Windows gave me the following error message when trying to enter the second character of the key "Some of these characters can't appear in the product key." I'm wondering if the letter "I" is no longer welcome????

Dear valkyre,

Thank you for your reply and attempt. I understand that you can't seem to activate using the OEM key at the moment. I reviewed the link I sent you in my last reply, and more users reported the same problem, and they all activated using the OEM key. This may be a problem with the update to 24H2.

I suggest trying to contact the customer service staff and tell them your current situation, that the activation failed after the update to 24H2, and tell them your key type. See if they have a solution.
