Lets see how we can change this button to another option.
In Windows 7, you can change the Shutdown button to a different action, these action can either of the following five : Log off, Lock, Restart, Sleep, or Switch user.
I had this set to Restart, which is most convenient for me. Recently (maybe due to a Windows Update?), it changed to Log off, and the "Power button action" dropdown is grayed out so I can't change it. Any ideas?
perfecto muy util gracias
