After starting the virtual machine "Updating your Windows Virtual Machine" window lasts forever.
- Virtual machine misconfiguration;
- Windows corruption, perhaps BSOD in the background.
Open VM configurations, go to Hardware -> Boot Order -> and paste in Boot Flags box:
- Start your virtual machine.
If it crashes, Open VM configurations again -> Hardware -> Hard Disk 1 -> change its Location from SATA to IDE or vice versa.
