Follow the following steps to shutdown your Computer with ultra-speed
1. Open the Registry Editor by clicking the Start button, typing regedit into the
search box, and then pressing Enter.
2. In left pane of Registry Editor, go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
3. In the right pane, right click on WaitToKillServiceTimeout and click on Modify.
4. Type in a number between 2000-20000 (2-20 seconds) and click on OK.
NOTE: The default time is 12000 (12 seconds).
5. Close regedit.
6. After rebooting (restart) Windows the new settings will take effect. The time to wait
for terminating services will be faster and shutdown won’t drag on forever.

quickly, then repeat the above steps and increase the time (Step 5) a bit.
