Very annoying computer virus prank which can easily freak someone out.
Try this only on a virtual machine, do not create this on any public computer or unknown person's computer.

Command on Shortcut.

cmd /k shutdown -r -t time_in_second /c "Your Message"
Like cmd /k shutdown -r -t 250 /c "Your custom message to show on the screen"

Do not assign a time duration of fewer than 4-5 minutes less than 300 sec otherwise, it will become hard to abort the automatic shutdown. Then boot into safe mode and delete the shortcut.

After your Prank is done revert everything back to original -
1. Delete shortcuts from startup folder & desktop.
2. Enable Desktop icons and my computer icon
3. Reset mouse & taskbar settings to the original.
4. Change the Background.
This is harmless and you can easily revert the changes.
Note: It is advised to create a system restore point and take a full backup before following any Windows tutorial.
