The Short Version (Win 9x)
The shortcut command line should be as follows:
For a shortcut to RESTART Windows:
C:\WINDOWS\RUNDLL.EXE user.exe,exitwindowsexec
For a shortcut to SHUT DOWN Windows:
C:\WINDOWS\RUNDLL32.EXE user,exitwindows
The Long Version (Win 98/ME)
Tip from Bill Blanton & MS-MVP George Aker. See also MSKB 234216.
The command line should be as follows:
C:\WINDOWS\RUNDLL32 SHELL32.DLL,SHExitWindowsEx n
Where n is one of the following values, depending on the task you want to accomplish:
n=0 LOGOFF: Shuts down all running processes, logs the user off, then restarts the Windows shell. (Same as Logoff on the Start Menu.)
n=1 SHUTDOWN: Shuts down the system to a point at which it is safe to turn off the power. All file buffers have been flushed to disk, and all running processes have stopped.
n=2 REBOOT: Shuts down the system, then restarts it. (Same as Start Menu | Shutdown | Restart.)
n=4 FORCE: Forces all processes to terminate — in effect, shuts down all running programs. When this flag is set, Windows does not query running applications to inform them that Windows is shutting down. This can cause the applications to lose data, therefore, you should only use this flag in an emergency.
n=8 POWEROFF: Exits Windows, then turns off the computer’s power (provided the computer supports the power-off feature).
n=-1 RESTART EXPLORER: Quickly closes Explorer (i.e., the Windows desktop), then lets it restore itself.
These values are additive, in the event you want to do two of them at once. There are varying reports of success with some of these options. For example, inconsistent behavior reported with option 8 may indicate a different behavior with the powerdown system on a particular computer. The solution for this usually is to request both a shutdown and a poweroff by using n=9 (adding the 1 and 8). (Tip from MS-MVP Tom Porterfield.)
