Want to add a dedicated Windows internal SSD to my Hackintosh. What do i need to know?

I set up my Hackintosh earlier this year using Vanilla method.

Here's my parts: i7-8700 CPU with integrated graphics, Motherboard is Z370N Wifi Mini ITX, Crucial 8GB RAM DDR4-2666, currently my mac OS is running from a Samsung 970 Evo m.2 SSD.

Dumb questions:

1. Will integrated graphics in the CPU work on Windows?

2. Will any of my parts conflict with Windows?

3. How do i set it up so i can choose which SSD to choose on bootup?

4. Are there any risks to adding an additional hard drive that's Windows?

5. Will Windows run off ANY model SSD or will i have to be mindful? I haven't bought the SSD yet

6. Which Windows is the best (7, 8 or 10? Or something else?) I hate auto-updates? I wont be gaming, just audio editing use and web use

7. I currently have 1 stick of 8GB DDR4-2666 Corsair. I'm gonna buy another stick. Does it need to be the same type/model/size as i already have? Or can i choose anything and it will be compatible?

Thanks for any information.

If there are some resources out there that would help me then link me up. Cheers
