Windows 10 guest 64 bit reboots itself on 5.1.12 win 7 host

[Papolytic]

After updating to 5.1.12 64b Win Pro 7 host: My Win 10 (either stock or insider) will have a 100% reproducible crash/reboot within a minute of bootup.

The nature of it seems to be connected to the guestTools .12 or latest testbuilds. As soon as I install the .12+ guestTools with the 2 new sub-installs for graphics, the crashes begin. I've check with other users and they also have this problem when using 2d & 3d & guesttools.

I've got a lot to attach (or copy in here) from the last crash:

Workaround:

Sometimes it's possible to run indefinitely if I don't create the VM with 3d or 2d enabled and don't install guestTools. The guest doesn't take lightly the "modification" from 3d to NO_d, so it's best not to install them if you want to run, be able to do updates to the system, work on it, etc. Low resolution is to be expected if you do this.

Tested on 5.1.14 : Same problem.

Just to clarify:: Of course, I didn't expect an unlooked at problem to be addressed, and for that matter, an unconfirmed problem (aside from whatever is happening with me).

For some more details I added this morning, it's worth a look at a problem I added to Windows guests:: ​https://forums.virtualbox.org/viewtopic.php?f=2&t=81477

If I can figure out how to, I'm going to mark this closed since I can't replicate it today. I made a clone of the VM so I wouldn't lose anything, added the 5.1.14 guesttools, and it worked fine for an hour. So it goes.
