Vista and Ad-aware 2007

As some of you may be aware, Ad-aware 2007 implement "aawservice ", which starts with Windows, and eats up a good chunk of resources.
This, I don't like, and I tried to do something about it. This is what I did.
In "services.msc ", I stopped "aawservice ", and I set it to "Manual ".
After that, when you try to run Ad-aware, it gives you an error. A solution was simple. I right clicked "Ad-aware2007.exe ", and under "Properties>Compatibility ", I put a checkmark next to "Run As Administrator ".
Now Ad-aware will run either by double clicking "Ad-aware2007.exe ", or from its shorcut.
The problem is, after running Ad-aware, "aawservice" will stay running until next reboot. I'd like to have it stopped after I'm done with Ad-aware.
In Win 2K, I had a simple batch file:
@ECHO OFF
Ad-Aware2007.exe
sc stop aawservice
@echo Done
which I used to run Ad-aware. When I was done with Ad-aware, the above batch file would stop "aawservice ".
However in Vista, it seems to impossible to set ".bat" file to be run as Administrator.
So, when I try to run the above batch file, command prompt window opens for a second, executing batch file, but Ad-aware won't open.
Any idea, what I'm doing wrong here?

 

Problem solved!
I changed batch file a little:
"C:\Program Files\Ad-Aware 2007\Ad-Aware2007.exe "
net stop "aawservice "
Actually the above change is non-esential.

What IS esential, I right clicked on the above file, and then I clicked "Run As Administrator ".
Ad-aware opened correctly, and what is most important, "aawservice" stopped upon exiting Ad-Aware.
The point is, if you run the above file normally, net stop "aawservice " command won't be executed.

Then, as a cosmetic move, I right clicked on my batch file, then Properties>Shortcut>Run, and I set it to "minimized ", so it doesn't open on my computer screen.
Secondly, I clicked on "Change Icon ", navigated to "Ad-Aware2007.exe ", and changed my batch file icon to Ad-aware icon.

Cute, huh?....LOL

 

All I can see in that thread is:

The service uses less resources when not scanning.

which doesn't satisfy me, since I see absolutely no reason for some application to run a service on my computer, while I'm not using that program.
This is about my general rule:
I want on my computer only something what I picked up to be there.
