I hope this doesn't happen to you, but on my Surface pro 2 and 3, I was pretty much forced into Win10. The Win 8 updates, would just spin away and never make a connection to microsoft. After several tech sessions with Windows, I gave up and moved to Win 10.
On my 15" Mac Pro on which I have bootcamp and had win7 64 installed, the same issue happened, net, the system would never connect to Microsoft. Again, I just gave up and moved on to Win10.
My main production machine, is still win7 and I have the control panel on it, as I never plan to move it to Win10 or anything else.
However the web is full of folks complaining about the sudden in-ability of win7 8 machine not being able to connect to Microsoft and get the necessary updates.
