There is no other supported desktop/CI/etc. solution for Windows on ARM. (Mac mini with Parallels/VMware is a popular unsupported alternative. It may still be your fastest.)
Seems like a truly decent machine (ordered one) but I'm not sure if there's remaining appetite for Windows target-specific development. After years and years of development platform missteps and PC usage pattern changes, I fear web (electron, etc.) has become good enough for Windows users.
