I use it a lot. Win and start typing to launch just about any app or open any document is really handy. Win and a number key launches or switches to that app pinned at that position on the taskbar. Win+L locks the screen whenever I get up from my desk. Win+Shift+S starts the screen clipper. Win+Left/Right snaps an app from one side to the other, win+shift+left/right switches between desktops, Win+Tab lets me drag apps from one desktop to another and see what's open where if needed, Win+E opens a new explorer window, Win+. opens the emoji keyboard. Those are just the ones I use almost every day, I probably use a few others a lot as well.
