I find that Windows itself is pretty easy to install. But all the drivers and apps are a PITA. Since each PC differs I can't be exact. I can share I install the OS, then motherboard drivers (NO! Microsoft doesn't do this for us!), audio, video and so on. Finally I see if I need helper apps like Intel's RST.
The maker of your PC should answer what it needs and in what order. I can only give the generic answer.
Good hunting,

I have included youtube links showcasing my problems, not including Audio/Video Delay when watching digital movies.

I've been having issues with my computer doing some strange stuff and I can't get it to go away. I went 15 hrs testing my overclock on Prime 95 with no problems, rolled back drivers, 970 GTX SLI overclock changes, I changed my mouse from a wired to wireless, new ram, Malwarebytes Virus, you name it. I can't get this to go away and I don't know if it is a hardware issue or what.
I built a new computer using almost completely new parts, except for my hard drives. Two SSD's and a WD Black 7200 1TB I brought from my old CPU. The problem carried on to my new computer and it seemed to come out of nowhere. I formatted and erased my old Windows 8.1 and installed a new copy on my Samsung 840 PRO 128 GB. I have not been able to get it to stop.
I wait about 30 minutes, and when i turn back on my computer, ALL the problems are gone. If I need to shutdown or the computer goes to standby, there is always that chance I will get those problems in the video links I provided. Any help appreciated.
