I've asked various people that work on computers & no one has a reasonable

Hi wasbit,

It's always hard to tell if any one setting made a difference, but in my
BSODs, the two factors which _seem_ to cause the most problems a
a) At the time of BSOD, "something" in the reboot is destroyed, and,
b) The more it reboots on its own, the more it "seems" to be destroyed.

Hence, I just now added a few more "protection" mechanisms, as shown below:

o Disable autostart after updates:
Win+R %windir%\system32\taskschd.msc /s {ctrl+shft+enter}
Task Scheduler Library Microsoft Windows UpdateOrchestrator
Right click on the task named "Reboot_AC" & click "Disable"

Note: It used to be called just "Reboot", as I recall.

o Disable autostart after crashes:
Win+R control.exe {ctrl+shift+enter}

CHANGE FROM:

CHANGE TO:

OK OK

In summary, in this situation where random BSODs destroy the ability of the
Windows machine to boot, what "seems" to help is preventing the machine
from rebooting out of our control.
