Please see my comments to the answer by Abhinav. I tried to create a manifest and found that it works as I thought.
If you need elevated execution level "requireAdministrator", it will simply request your confirmation via the UAC dialog immediately and by default. If you do not request the elevated privileges but try to perform any operation which actually requires such privileges and do not execute the application with elevated privileges, you will simply get an exception at the moment of the illegal access.
It looks perfectly logical. If you could be able to do some miracle trick to work around UAC confirmation at the level of the application itself, based on the content of application's executable modules, it would totally defeat the purpose of UAC.
However, instructions to "disable UAC for certain applications" circulate. Please see:
I never tried it, but just because I consider UAC as of Windows 7 quite well balanced between ease of use and security.
The radical way to disable UAC is to disable it totally. You can find the related recipes here:
I would strongly discourage doing so. Anyway, you decide.
