Other than the fact that the .png format is the default, I quite liked the new WinKey+PrtSc "take and save a screen shot in the Pictures\Screenshots folder" functionality.
When I last tried to take a "window shot," which one used to do (and still can, but without automatic saving with ALT+PrtSc) using WinKey+ALT+PrtSc it did not work at all. This morning I thought I'd try again to see if that functionality has been added, and it appears it has, but when I use it I get a message from Xbox Gaming Overlay and the resultant screenshot is saved in the Videos\Captures folder. I am just wondering what happens for others if they use the WinKey+Alt+PrtSc function when focus is on a non-maximized window or a dialog box.
All of the above is under Win10 Home, 64-bit, Version 1803, Build 17134.81
