I updated Windows 11 to the 24H2 version, the activation for it was removed

I mentioned that I tried this step, it didn't work. The only option I had is to revert to the 23H2 version, in which my Windows is still active. I'm not going to upgrade to the 24H2 version, hopefully they will fix this issue in the next one's.

Sorry my bad, I totally left out this detail - it is NOT the key you found in registry. It needs to be the key on the sticker on your device. They are not the same thing.

Per licensing terms, when computer builders use OEM-NSLP keys, they must put the stickers on the device they build and sell. This sticker can be located on the back, see if you can find it.

Troubleshooter will not work for your scenario as it is for digital license only.

Did it work???

go to there where you can activate it and select troubleshoot it should help, it helped me

I'm having the same problem, were you able to find a solution?

Ok here is what worked for me.

I had gone through every other advice that was suggested in the internet and I did make sure that my current device was linked to my microsoft account. None of the suggested options worked till i did the following:

I went to the Microsoft Store and got an app called ShowKeyPlus. When you run it, in the first page there is a field called "Original Key". Copy that down and then go to System > Activation (just go to Settings and search for activation). Then i clicked "change product key" and entered the string i got from the Original Key field in ShowKeyPlus and then after an hour long of frustration it just activated.

Hope this helps.

Hi this is just getting ridiculous. Seems like this update 24H2 is a virus that is blocking my internet when I try to activate, troubleshoot or download this ShowKeyPlus but only when I,m performing these actions. I uninstalled these 2 updates work fine without the logo "activate windows" up until the next restart.

Thanks Emily,

This worked for me. Easy fix.

Hey Emily!

I tried for HOURS to get the new 24H2 update to work for my custom-built PC, as I originally had a physical product key for the 23H2 version. I just tried your method, and it solved my problem almost instantly! I didn't think I'd have to "Change" my product key when it technically hadn't changed at all. THANK YOU SO MUCH!!!!
