When we used to hit the Turn off button in start menu of Windows XP, it used to present us with a optional screen to chose between actions like Turn off the PC, or to reboot or stand by mode.
How ever with Windows 7, Microsoft is done with the second tire system of shutdown verification and presents you single click operation where you click the shutdown button in Windows 7 to turn off the computer without second verification like what used to be with Windows XP.
What it actually did, is it increased the number of accidental shutdown a lot. Where some user mistakenly clicks the “shut down” button available right in start menu.
How to prevent accidental shutdown ?
One of the easiest method is to remove the shut down button from the main menu and put it in the sub menu beside it.
Right click on start / task bar and click properties from the menu.
From Taskbar and start menu properties, go to the start menu tab to select a suitable option to replace the shutdown button with the available options of power button action.
Now if you click on start, you may find “Lock” or the what ever option you have chosen has replaced the shutdown button and placed the shutdown button in sub menu to prevent you accidentally clicking shutdown.
