Nah man, they put out another update that made the Get Windows X thing auto install. I got texts from about 4 people asking why they are on windows 10 all the sudden and all of them swear they didnt do anything.
I been using GWX Control Panel on all my systems that i didnt want to update, and its kept them all safe.
The good news is, once its installed if you dont want it you can go Start > Settings > Update & Security > Recovery and for one month you will have a button to go back to your previous OS. Just dont wait too long, or it disapears after a month.
