You might want to search the Windows sites or forums. I have seen some reports of drag and drop issues in Windows 10.
It turned out that the reason for the loss of Drag and Drop in Windows 8, and 10 is very simple this "User Account Control or UAC." This “controller” constantly interfere in my work and it is the first thing that I turn off after installing Windows.
After researching and trying different things on my own, I don't know exactly how but, I figured it out. I right clicked on my Adobe Illustrator CC desktop shortcut and clicked on "open file location" once there I made a shortcut using that source and guess what? now I can drop an .pdf into it and it actually opens it.
I notice that in the shortcut properties under (shortcut) the path that's in the Target field is different than the shortcut created automatic by when I installed the adobe applications.
I can now drag and drop my files on the application and it actually opens.
I didn't know there was a difference. Javeps is the MAN!!!
- Creating a Desktop Shortcut directly from the Target: "C:\Program Files\"Your Application.EXE" Folder fixed the " Drag and Drop File on Application Shortcut " issue. ! ! ! !@@@@
