Best drivers to use for the HX100G (64gb)?

I just bought a HX100G and was curious about the best drivers to use before I started setting it up.

The guides here are just for the HX99G and I believe a few things are different enough that other drivers might work better?

Also, would people recommend Windows 10 or Windows 11? I suspect the PC comes with no OS, so I'd need to get one. I am not a fan of the latter but I know Win 10 is ageing out of support very soon (even though I run Win 7 still on a machine just fine!).
