Google "Windows 10 how to disable wake timers" to stop it waking up for updates.
As to the rest, your choice. I have yet to see any issue with changing my default programs unless it's from one of the HUGE updates.
I'm trying to stop windows 10 from updating on my Acer desktop and stopping it's hidden critical updates and the changes it makes to my default programs. I will be in control of my hardware even if it means, gulp, Linux, which I never was happy with when I tried it 2 years ago. I realize i don't own the MS software but I don't think going backwards is for me, I'm too old for that, been using computers for 33 years, they haven't beat me yet.
My issue started when my computer would start at 3 am from a hibernated state almost every night and my default programs would be back to MS factory setting, this was unacceptable. The major change I have now implemented as a starting point is installation and use of Zone Alarm firewall. Now I will see what happens. Any thoughts welcome here and I'll share my findings here. J
