You can make it 'force shutdown' as in force all apps & services to close rather than waiting for them. Here's a snippet from a website:
Often what holds up the Windows shutdown routine is the operating system waiting for background and foreground processes to close. Microsoft has tried to alleviate the problem by introducing a Force Shutdown command in Windows 7. This kicks in after 12 seconds by default.
You can speed that up, however, by changing a registry setting. Open the Start menu, type 'regedit,' and then click the regedit.exe entry that appears. The Windows Registry Editor opens.
In the left-hand pane of the Registry Editor, expand the HKEY_LOCAL_MACHINE tree, and then expand System, CurrentControlSet, and Control. With the Control branch highlighted, look for the entry WaitToKillService in the right-hand pane of the Registry Editor. Right-click it, select Modify from the pop-up menu, and from the resulting dialog box, change the value 12000 (for 12 seconds) to something lower.
