Did you by any chance apply the Windows 8/8.1 Microsoft Media Center key in control panel? That can change the Windows version back to 8.
Seems like I will be offered the upgrade whether I have 8 or 8.1
I wonder how many programs will continue to work.
Thanks for the reply!
You're fine at 8.1 so no worries there.
Users with Win8 installs might get another eMail urging them to update to 8.1 before Win10 goes live.
Lots of programs are working - here's what other members have reported (working / not working)
It might be quicker if you installled them and see what happens. If one doesn't work, please post the information in one of the threads I provided.
Win10 is a sandbox - have fun - try lots of things - let others know what you find out - don't run with scissors
