I ended up running Never 10 to all my Windows 7 systems.
My situation is that Windows 7 does everything I need it to do, and Windows 10 is lacking. In fact there is no feature that 10 has that makes it worth having to have. So I am pretty much sticking with 7. Before the free upgrade period is expired, I will clone a drive and upgrade that cloned drive to 10. But will run 7. Someday when there is some sort of need for 10, I can simply swap drives and be on 10 after the deadline. And if I never go with Windows 10 then I can format the drive and use it for something else.
Windows 10 has been a let down personally. Additionally Microsofts pushy attitude with 10 in which they tried to force upgrade systems of mine to 10 soured my opinion of Microsoft as a business I can trust. I use to like Microsoft and now I am feeling more and more driven to Linux OS's. I have been using Linux Mint more and more. If they made a DirectX that was open source for Linux it would be sweet as for OpenGL just doesnt perform as well as DirectX for video games.
System I downgraded to 7 from 10 was a
AMD FX-8300 3.3Ghz 8 core
Biostar A960D+ AM3+ Motherboard
8 GB G.Skill Ares RAM ( 2 x 4GB 1600mhz )
240GB SSD Crucial M500
EVGA Geforce GTX 260 896mb superclocked 216 core

I get a solid 60 fps with world of warcraft with windows 7 but windows 10 with nvidia driver I get 40-45 fps in the same area that performs better with 7.
