Shutti Shutdown Booster acts as a "turbo button" for this final phase of your computer's operation. Instead of manually editing the Windows Registry or navigating complex Group Policy settings, this software automates the optimization of shutdown timeouts.

Shutti hooks directly into the Windows Power Management API ( ntdll.dll and powrprof.dll ). It sends a "Force Shutdown" command that specifically ignores the WM_QUERYENDSESSION message that usually halts the process.
