Just this December, following some Win7 alarming freezes, and years of not being able to boot with peripheral hard drives attached,
I was advised to switch my DualXeon, 4 Graphics card machine to Win10.
The tech guy that advised this ran into many headaches trying to upgrade the existing Win7. Ultimately, he did a clean install of Win 10.
More hassle for me, as I had to dial everything in for a week or two, but.....
Honestly, so far so good. I am told that Win10(pro) allows for more efficient use of the dual CPUs, and at some point Win7 support will fall off.
I disabled many of the unnecessary bells and whistles of Win10 to make it run a bit more quickly.
Hope this helps
UEFI boot may be also helpful. Moreover if you are C4D user make sure to turn off internal renderer... And always set power plans to max performance.
Indeed a good clean windows install is a key for solving some issues and keeping a backup...
