To Speed up computer shut down process you will have to do some adjustment in Registry Editor.
Before you change anything in registry it is strongly recommended that you back it up in case you run to any problems. To open registry Editor go to Start , type "regedit" and click on it.
If that doesn't work for you than you can follow this commands:
Start - type Run and open it , now inside run dialog type "regedit" and hit Enter.
Once you manage to open Registry editor follow this path:
HKEY_LOCAL_MACHINE - SYSTEM - CurrentControlSet - Control
Inside Control folder find file WaitToKillServiceTimeout and change its value.
As a default mine was 12000 but I changed to 2000 and noticed difference.
