Open Windows Shutdown Dialog

Here is a one-liner that opens the Windows shutdown dialog:

(New-Object -ComObject Shell.Application).ShutdownWindows()

And with this one-liner, it turns into a new command named “bye”:

function bye { (New-Object -ComObject Shell.Application).ShutdownWindows() } 

If you place this line in your automatic profile (start) script located in $profile (you may have to create the file initially), when you are done scripting you can now simply type “bye” to shut down your Windows session.
