UPDATE: 2023.02.01 19:33 service restored, thanks to Remote Desktop (for a change).
Same ol, same ol. Windows Update -> Windows Explorer (Desktop in reality) crashed -> black screen
Hopefully, we can get somebody down there to reboot it, but that's not a guarantee.
I hope to replace that p.o.s. laptop with a more powerful machine, but will need time to make the preparations. Good luck with that.
If I could get VSThost to run on linux I'd get rid of Windows yesterday!
