I can vouch for the Win10 Snip tool. For years I have been using a free screen shot program I downloaded in the late 90's. I was using it for my update to the documentation. It is a TSR that is activated by the Print Screen button but it required me to save the screen shot then open it with a drawing program and copy and paste it to use.
My daughter suggested I try using the Snip tool, it automatically puts the screen shot on the clipboard letting you paste it directly or save it if you wish. This saved me a lot of time adding screen shots as I could have the game file I was using for the screen shots opened along with Open Office, take the screen shot then paste it. It was extremely useful for adding the new menus since I could just do one, add the text, do the next and didn't have a lot of saved jpg files.
About the only improvement I've found in Win 10.
