One thing Windows (er... Microsoft I should say) does well is steal ideas.  Here's a visual technology that has been around in other platform(s).  One thing Microsoft is finally FINALLY doing right is not just making visuals pretty but actually making those purrrty visuals a functionally useful thing.

Here's one.

When you have multiple windows you used to have to Hold down Alt and press Tab and go through each window if you wanted to see the window you were looking for (if you had multiple of the same program for example)

Now to make that visual appear so you can easily see all windows open at once and easily scroll to the one you want, Use the Windows Key+ Tab.

Step1: Down below on your keyboard right next to "Alt" is a key that looks like windows logo.  Hold that down and then tap press "Tab" key right next to Q and let go of Q after you tapped it but do NOT let go of the windows Key.  Keep holding that one down.

Step2: While you are still holding down that windows key, if you press Tab again then the windows switch in position forward.  If you press Shift+Tab instead then windows shift backward.

OR instead of tab, you can scroll the mouse wheel.  It's much faster.

Step3:  When the window you want is at the top most position and you can see all its contents, you can let go of the windows key OR mouse the pointer over the window you want to switch to and click it. (mouse method works even if the window you want is not at the top)
