Bat file running as administrator does not work

Here is my test bat file:
@echo off
echo\
echo "Hello David"
echo\
pause

If I run this very simple bat file in a user account or admin account, or in an elevated command window, it works fine - I see the text and the pause - no errors. But if I run the bat file as Administrator (mouse right click) or use a shortcut to the bat file that runs as administrator, the window appears and immediately disappears. I do not see the text or the pause. Why? What am I missing?

I found the answer to this very annoying issue in my case was simply that the name of my batch file contained an Ampersand ("&") and Windows 10 (and Windows 7) for some reason do not like having this character in the file name when combined with the "Run as Administrator" option - either from the right-click context menu, or ticked in the icon. Stupid, really, since everywhere else an Ampersand seems to be a valid character for a file name....

Thus the reason that "Pause" didn't work was because it never even opened the file to begin running commands.
