What to do when installing a new OS and mobo drivers are only for older oses?

When I got my mobo/built my rig I got an asrock extreme 4 gen 3 and all the drivers for it were for windows 7 since it was the newest os at the time. Now 8.1 is out and 10 will be soon, and I plan to get that when it comes out.

Thing is all the drivers http://www.asrock.com/mb/Intel/P67%20Extreme4%20Gen3/?cat=Download&os=Win764 are for windows 7 there are some for 8(not 8.1 though) http://www.asrock.com/mb/Intel/P67%20Extreme4%20Gen3/index.asp?cat=Beta but it looks like only the usb 3.0 driver has been updated. Should I just install the windows 7 drivers when I get 10 or am I SOL?

I thought you were talking about 20-40 year old motherboards. I've literally never installed anything from the motherboard vendor site. You'll have absolutely no problem with that P67 mobo, I personally guarantee it.

And most 7 stuff works with 8/10 anyway.

Don't quote me on this, but I think windows 8 and 8.1 share the same base kernel, so the drivers should work.
