Why does Windows 10 Enterprise (LTSC) Evaluation randomly auto-quit in a VirtualBox VM??
works for several minutes (from 10 to 30), until it was possible to notice exactly, and the system shutdown begins ???

PS: VirtualBox 6.1.2 @ Linux Mint 18.3 XFCE (on a laptop)
allocated 1 core and 1.5GB of memory for the virtual machine.
recently downloaded the 10ki image from the MS website - 17763.107.101029-1455.rs5_release_svc_refresh_CLIENT_LTSC_EVAL_x64FRE_en-gb.iso
Windows is clean ! Turned off any shutdowns in the power settings.
