Hi Eric,
I run a similar setup. Windows 10 with The Sky X, Maxim DL and PHD2 controlling an Astrophysics AP1200 mount. It all works very well. I find Windows 10 very good and stable, other than occasional annoying updates. I think you may be able to prevent updates by setting the internet access as a metered connection, though I am not sure if that still works. I tend to spot updates before hand as they will usually happen on my indoors PC first, and then run the update in the daytime.
Cheers,
Andy
