> Windows take a screenshot of everything visible.

For the record, it's still not a region selector but there is also alt + printscreen to take only the visible windows.

There's also the built-in Snipping Tool, which allows you to take a screenshot of a selected region. I use it a lot at work.

Apparently, Windows 10 Creators Update comes with a shortcut to capture a region, Ctrl + Shift + S.
