Remap the F7 key to execute the Win + Shift + S shortcut
Solution 1:
I've just remapped my PrintScreen button to Win+Shift+S using the Keyboard manager on Windows Power Toys.

I've used AutoHotkey before and this would do the same job but Power Toys is simpler and quicker I'd say... WPT also has a lot of other nice functionality so it's worth checking out.
