This is the OneNote screen clipping tool. If you don't have Office, Win+Shift+S doesn't do anything.

This is a super useful tool, but most often I paste into mspaint and mark up from there.

Since the creators update this is a system wide shortcut afaik. So it should work without OneNote.

Doesn't do anything for me. Running the creator's update without OneNote or Office installed.
