I'm sorry if the title of this thread is misleading, but I am not going to show you step by step how to fix the HEM for Windows 7/UAC. I might do that some time in the future but that's too much guessing.
What I am going to do is just post a link to another web that explains how to patch ANY app so that you still can have UAC running but won't be bothered every time you want to start an App, like HEM, from which you know it is perfectly safe.
The tutorial was made in 2008 for Windows Vista, but since Windows 7 has a lot in common with the previous version it works perfectly.
So enough talking, here's the link

Another option is to use the Norton's UAC Software, but I guess you'll have to pay for it ...
