Windows 11 deactivated after 24h2 update

I have exactly the same problem. Something needs to be done about this problem quickly. My PC was also bought with an OEM version pre-installed. I have the Activation Key but Windows does not recognise it.

I'm having similar issues. I support an organization with over 200 workstations and I'm seeing a similar issue with upgrades as well as fresh installs. In previous versions of Windows 11 installations, it would look for a digital license and automatically activate once loaded into the operating system. After regretfully downloading a fresh copy of Windows 11 24H2 to distribute in my organization, I'm getting several machines suddenly prompting for a product key, which was never the case with previous versions. This is expected if I was building a PC from scratch. A prompt for a product key then would be expected, and certainly nothing new. But this is NEW with 24H2 in that something has changed so that it either no longer checks for a digital license or only accepts brand new OEM 11 keys. I hope they fix this ASAP because this was not an issue with previous versions of 11.

It is appalling that this is still happening. Six weeks after this initial message, I have also updated with Windows 11 24H2 and face the same problem.

It's the first time I've had a problem with a Windows update, and I've been around a while, but surely this is going to be expensive for Microsoft?

I started actively trying to solve this issue just now. No luck so far. Have you had any success in your Org?

I have not tried to solve this. Waiting on MS to do their job... Sigh
