Everyone loves shortcuts. Sometimes you have a bunch of stuff running, and you want it all to go away so you can get to your desktop. Simply pressing Windows key + D will minimize everything you have up, which will save you some time pressing the minimize button for each window.

And if you're addicted to using emoji, desktop operating systems support them natively just like mobiles do. On Windows, press the Windows Key + . (period) and on macOS Cmd + Control + Spacebar. An emoji panel will appear so you can carry on as usual using all the expressions you want. Very professional!
