A particularly quick way to shut down Windows 10 – with a double-click – is to create a special shortcut to shut it down.
Right-click on a free space on the desktop and select the New/Paragon icon from the local menu. In the Create Shortcut window that opens, type shutdown /s /t 0 and click Next.
The s parameter will ensure the shutdown, the t 0 parameter specifies that the shutdown should take place after 0 seconds. Give the shortcut a clear name, such as Shutdown, and save it by clicking the Finish icon. In the future, double-click on this shortcut will be enough to shut down Windows.
The shortcut can be saved in the taskbar or in the Start menu. To do this, right-click on it and select the corresponding entry.
