You might be one of those Windows 10 Power Users who wants to minimize all open windows quickly in Windows 10. Instead of clicking the minimize button for each of the open windows one by one, you can minimize all windows at once with a quick shortcut key.
How to Minimize all Open Windows quickly in Windows 10?
You can use the shortcut key (WINKEY +D) to minimize all viewable applications and windows at one go. This shortcut key is like a toggle key where if you use the shortcut key again, it just puts everything back up again.
Alternatively, you can also use WINKEY + DOWN ARROW to minimize the active window. You can use the same key back again to restore a maximized window in windows 10.
