In the Shut Down Windows 7 machines running some programs will take the time to save data and close the program before the shutdown. By default in Windows 7 at this time was 12 seconds. But here you can reduce this time to speed up closing the program. To do this, you can use the Registry without software support.

Start, choose Start> Run (or Windows + R key combination) type Regedit and press Enter. In the Registry Editor window in the left pane to open HKEY_LOCAL_MACHINE and select the directory SYSTEM> CurrentControlSet> Control. Double-click the item WaitToKillServiceTimeout in the right pane of the Registry Editor, in the Edit String window you change the value to 2000 (2 sec.) In the Value data. Finally click OK to save the data and establish and close the Registry Editor.
