The next time this pops up, click to follow the prompt and go onto to reactivate the computer.
I tried this, but the popup still persists.
You mean you re-activated, but you were still getting pop-ups saying that your copy of Windows was not genuine?
Did this problem arise after installing KB3024777 or before?
Yeah, I tried re-activating Windows, which was supposedly successful. The problem began on the same day that the updates were applied. So far, I haven't received the popup after I did the successful system restore. I'm hoping my luck holds out, and the popup won't appear anymore.
Below are the updates I plan to install for December. Note that I hid all "Update for Windows 7" updates, because I don't think I can trust them anymore.
Geez Microsoft, is this whole mess some conspiracy to get Windows 7 users to upgrade?
