A function/shortcut used in the Windows operating system. Pressing the Windows Key and the letter 'D' simultaneously will minimise any folder/program/window that is on the screen at the time.

Due to this function's popularity with risk-taking pornography fanatics (to quickly hide evidence of unscrupulous activity), it can be humorous to shout "WINDOWS KEY D" while entering a friend's room when you know they are using a computer.

Whenever making a congratulatory remark, this is what you say. Made popular by Kamala Harris when she and Joe Biden won the presidency.

Actually, it doesn't minimize all windows, it shows the desktop. There is a slight difference. When you maximize any window, all your former maximized/restored windows will open again. Window Key + M is actually the minimize all shortcut, however if an application has a dialog open, it will not minimize it.
