Often use it, especially windows key + shit + B to clear the GPU

I use it with the arrow keys fairly often to snap apps to sections of the screen.

Some terrible keyboards put it where alt should be and those should be burned.

I actually use it to open the start menu for a few reasons. Usually I do it to the press tab and the down arrow 5 times then enter twice, why? Because that puts your selector thingy on the sleep option as my keyboard doesn't have a sleep key. The other reason is I can just start typing some program's name and launch it without using my mouse. I don't do it all the time since most programs I need to use the mouse to keep using anyway, but sometimes I just want a calculator or notepad++ and the search function works well enough for those

I use it as an additional modifier key, Super. I bind stuff to its modified keys in my window manager, but also emacs intercepts them before the window manager and I have some bindings that do more or less the same thing in both emacs and my window manager. The operating system has no "intentions" for how I am meant to use the Super key but this usage is within what the designers anticipated for certain.

Only if my window has gone missing and I need to winkey + arrow keys it somewhere to get it back.

Other than that, no.

I mean early days, most of us pulled it off or disabled it so we wouldn't hit it by accident while playing FPS games.

I use it EVERY day at work. I use the Windows key + L to lock my screen when I walk away from my computer. I work in IT and setup new computers for new employees and I access the software from a server that I access through Windows Key + R. I could use GUI clicks to do both things, but this is the absolute quickest.

the super key is one of my most used keys.

All the time. For shortcuts and opening programs.

Hot key Moving a game from monitor to monitor is pretty much impossible otherwise I thought.

Not here. I don't use Windows and so I rebind the Win key (or, Super) for some quick functions.

Win + L to lock the screen
Win + K to blank it
Win + C for my calculator app
Win + T (and Ctrl+Shift+T) for a Terminal
Win + Left/Right arrow to cycle to the previous/next desktop

Bonus fun, I rebind the Right Alt key to a Compose key for typing Latin-1 diacritics in non UTF-8 applications. (Plus, I can't remember the U-codes)

In most linux tiling managers it is used with directional keys to nav windows and desktops.

Yes, I definitely do. I use it to open start menu and search, as well as using quite a few commands, run, snipping tool, moving and resizing windows, etc.

When win10 is no longer supported we will be making the leap to linux, and I really hope I can get much of this functionality there.

I have removed the key cap on my home keyboard. It's still possible to press but you won't accidentally fumble it when you hit ctl or alt.

I use a "normal" keyboard with a MacBook. I've rebound LAlt to be CMD and the Win key to be Option (to better mimic the MacBook keyboard). So theoretically I am using the Win key A LOT, just not for the intended usage.

Hey buddy, do you want to try some of this GNU/Linux?

nope, never. not even on windows boxes

The only time I used it is when I wanted to bring up emoji easier without copy and pasting them from a website. Otherwise I prefer to just navigate to whatever I need to open manually because I can't bother remembering all of the shortcuts. Since then I've changed the OS.

I'll use it if alt tab isn't working to get me to another open program. But that's pretty much it.

I also have my most used programs pinned to the task bar. And that bar is vertical, thank you.
