is there a way to roll back an automatic Windows update, or otherwise recover this hosed VM?
While I was away from my PC (Win 10 Pro host running Hyper-V), a Windows 10 VM it hosts decided to update itself. The VM had been working fine since it was created last year (with usual automatic updates) until now.
The VM boots to the login screen, then says "This might take some time" and "These updates help protect you in an online world" and "Leave everything to us" hahaha! (plus "Don't turn off your machine"). Some ten minutes later there's a popup:
Popup Title: "Location is not available"
Popup text: "C:\Windows\system32\config\systemprofile\Desktop is unavailable. If the location is on this PC, make sure the device or drive is connected or the disk inserted, and then try again ..."
Clicking OK to dismiss the popup gets a black desktop with only a recycle bin. Clicking the Start button does nothing. Task Manager shows no processes, and no users.
Winkey+R lets me run stuff (if it's on the path), internet is OK (ping, git, etc., work) but networking won't do NET USE (gets system error 1222)
Any ideas for diagnosing/fixing the problem would be greatly appreciated. This VM is my development system; I do have an old VM Checkpoint but will lose my tailored environment if I revert to that. Luckily all source files are in github
thanks
