Im sure you know this but in Windows 10 if you hold down Alt after hitting Tab the first time it’ll display which windows you already have open, and hitting just Tab again will cycle though them. You can even hold down Shift as well to cycle through the list of icons but in reverse.

I'm sure you know this, but, I think at least since Windows 7, while having the Alt+Tab "popup" open, you can use the arrow keys while holding Alt down to directly navigate to the window you want to open. Very useful if, like me, you have 20 windows of browser tabs open, and the application you want is in the middle of the list.

Yes - and you can also mouse over them and click now too. All three of these interactions are, imo, very intuitive and easy to do.

After the first Alt-Tab you can also use the arrow keys to navigate to the window you need.
