More productively, perhaps: does anyone out there have experience with upgrading an observatory computer from Windows 7 Pro to Windows 10 Pro? I would retrieve it home during the next cloudy spell, to take my time with it. Win 10 has its update concerns (the same idiots built it after all), but at least Win 10 updates don't seem to cut off PCs from the rest of the world.

The operational question: would you recommend a fresh install (wonderful but very painful, given the number of astro drivers etc required) or in-place upgrade (would that likely even solve the Updates problems I'm having)?

Win 10 is becoming inevitable, so I would guess this question of which upgrade path to take is timely for more than myself...
