I think there is a reason why UAC prompt is necessity. It is called security and it takes only few seconds to confirm yes (or no). There is no need to give access 3rd party software like this one to mix up your UAC settings.

Also if you think you don't need UAC at all, you can disable it by typing UAC in the search field on your taskbar and turn UAC off, drag the slider down to "Never notify" and click OK.

While in general it is better NOT to "work around" the UAC (or to even turn it off...), there are some situations when it is breaks your well planed workflow.

First: I must agree, I never tested Abylon´s´ tool - but there are 2 simple reason for this is
1.) I use "AutoHotkey" for this (and even sometimes use it working on "foreign" computers...)
2.) Abylon´s´tool is pretty heavy on space (and not portable, too)

How do I do it?
by just running a .AHK-script which runs all essential needed tools via simple 1-letter shortcuts! Only when AutoHotkey is initially run, I HAVE to answer the UAC question - all tools started later via AutoHotkey do no longer ask me again!
BTW:
For good reasons I prefer a special shortcut mode of AutoHotkey for "my" essential tools:
simply pressing an assigned letter for more than 0,6 sec. because I never found this to interfere with other hotkeys on any other machine I had been working on.
For those, who are interested in how this works, here is a short example for the letter "t":

$T::
KeyWait, T, T0.6
If (!ErrorLevel)
Send t
else
run TotalCmd.exe
return

Have fun
