WOW, thats just spectacular. I hope you are planning to protect it well under a good conformal coating

I used to trust Windows Update completely and for years it was a very useful service. Starting when they started pushing Win10 though it went downhill real fast and became in my mind a threat more serious than the threats it was meant to prevent. With Win10 consumer versions this is even worse and the automatic updates that happen without user consent are completely unacceptable. I turned off all updates ~3 years ago and everything has worked so much more smoothly. A computer should never *ever* reboot without my express permission.

It has only gotten worse despite Microsoft's lying assurances since it became a problem.  So far I have only needed to set the network configuration to "metered" to prevent inopportune updates and reboots.

I become very unhappy the first time a weeks worth of possessing time was lost.  Are people expected to even do work on PCs anymore?  I hope every person at Microsoft who thought this was a good idea gets lynched.

Much as they a PITA at times the typical 3D printer choice of Micro SD cards loaded with G Code beats having a PC hooked up to the machines especially when you might have one running for 10-20 hours on a job.

Time for CNC router controllers to go the same way add a bit more brain and a simple interface for jogging etc. and lose the PC from being tethered as a data storage device?

A better solution for 3D printers is stuff like Octoprint or Astrobox - Raspberry Pi loaded with the front-end software, so that you can access, monitor and control the machine remotely. But there the Pi isn't driving the stepper motors, only feeding the G code to the integrated controller (often some Arduino-like board). Mostly saves running around with the SD cards and saves you from having to sit next to the machine babysitting it while it works because it supports cameras - so you can watch it from elsewhere in the house.

And for cheap CNCs where there is often only a "dumb" controller that needs pulses for the steppers (often using parallel port!), there is e.g. Linux CNC or Mach 3 - put it on a small dedicated Linux computer and problem solved. Way more stable than relying on your Windows PC/laptop to keep going for many hours straight.

Of course, if you have money (and aren't afraid to mess with the wiring), there are dedicated CNC controllers too.
