QuickTime 7 Adds a %1 to Open With Menu Windows 8.1
The %1 is on .png, .jpg, .bmp .psd photo file types so most photo file types in Windows 8.1 open with list with the exception of .gif file type that has a correct QuickTime photo viewer icon and label.
Uninstalling QuickTime 7 makes that %1 go away.
