FRSPCShutdown

If you ever struggled with shutting your computer down from the "Start" menu and not in the barbaric "holding-down-the-power-button" mode or unplugging the unit altogether, you might want to use third-party software to help you.
That's right, some software solutions such as FRSPCShutdown were designed especially for this type of moment when you'd like your PC to be turned off but instead you're bombarded with unnecessary questions.

Shuts down your PC

As stated above, this application can help you perform a quick shutdown of your computer without having to open the "Start" menu. All you have to do is double-clicking the shortcut icon on your desktop or wherever you moved it after installation.
However, despite the fact that this app should perform a clean shutdown without any additional questions, messages or dialogs, it asks you whether or not you'd like to save your progress for whatever projects are currently opened on your computer.

No portable mode

Just like the reboot version of this app, FRSPCReboot, FRSPCShutdown doesn't come as a portable utility, meaning that you have to install it on the target computer, rather than placing an executable wherever you see fit, be it on your desktop, taskbar or start menu.
However, the installation process can be completed without significant efforts even by users who have no previous experience with operating a computer, since it comes with a wizard that provides handy on-screen instructions during setup. A desktop icon can be created or you can toggle it not to be generated during the installation.

Handy PC shutdown tool

All in all, if you're looking for an app that can help you shutdown your PC without navigating to the Start menu, you can give FRSPCShutdown a try. It's not portable unfortunately but can be installed quickly and used without efforts.
