Keyboard shortcuts are quite useful and make you work faster and more efficiently. There are several hotkeys or keyboard shortcut combinations which carry out different functions.
Minimize all open windows
Most Windows users know that, if you wish to suddenly minimize all your open windows, you can simply click on Win+M keys. Once you do that, all your open windows will get minimized to the taskbar.
To restore the windows back, you will have to press Win+Shift+M. But when you minimize all open windows using this keyboard shortcut, now when you right-click on the taskbar, you will see a new context menu entry Undo minimize all windows.
Clicking on Undo minimize all windows will also maximize all the windows again.
Minimize inactive windows
However if you want to only minimize your inactive windows, you can press instead the Win+Home key combo. You will find that all except your active windows will get minimized to the taskbar.
To restore the windows, just press Win+Home combo again.
