Alcohol 120% -- Under LUA you will get an Application Error or Alcohol 120% might report it is not registered. You won't be able right click virtual drive and mount images. Solution: Run As Administrator, open main interface and mount/unmount images from there.

Blackmoon FTP Server GUI -- to run the GUI you need to do Run As. FTPService will still function correctly because it is running as a Windows Service.

Diskeeper -- to run the GUI you will need Run As. Under LUA the Defrag Windows Service will continue run properly.

Nero Burning ROM -- You get the message saying that you need to install Nero Burn Rights. Because I didn't like to create another User Group in Windows, I just use Run As and everything works. If you are an extremist, you can still run Nero Burning ROM as a Limited User, burn everything you need using Nero Image Writer. Next time you log in as Administrator, you can burn all those NRG files and clear the source files.

If you are a developer, you will discover loads of other applications that won't run properly (for no reason) as a LUA. Most of these applications fails because they stupidly need HKLM to save program settings where as HKCU is the properly location to save those settings.
