This is just another Microsoft ploy to force people into using Windows 10. I just loaded Windows 7 Pro over Windows 10 on a new i7 7700k, Gygabyte K5 gaming motherboard. 2-19-2018
I had very little problem doing windows update. There was about 200 windows updates and 8 optional updates. I did the updates in batches of about 30. When I had a failure (about 6), I did that update manually. This computer and all 3rd party software run fine. Much faster than when running Windows 10.
Yes, I get the annoying message about compatibility on each restart. If you remember DR-DOS, it's just another MS fake problem. Before windows there was DOS for disk operating system. Microsoft DOS was loaded and then windows on top. A competitor wrote DR-DOS and it was less expensive. Microsoft added a warning to the windows installer that stated something like "Windows may not run correctly with DR-DOS".
Not true, but because people believed Microsoft, the writers of DR-DOS were forced out of the market.
If Microsoft wants me to run Windows 10 then I need a version without the spyware, Cortana, memory hogging built in programs, and have control over updates.
