-= Run WinVNC.exe At A Service Level=-
The problem was that the SC couldn't do it because it wasn't running as a service (system account). Well there is a dirty trick that I have found that works with 2000/XP systems. Now I'm not sure under what conditions this will and won't work. I haven't tested it that much (that's why I'm posting it here) you guys give it a try.
For testing replace ONECLICK.exe with your filename that you plan to use as your singleclick.exe. This batch file tricks windows 2000/XP into running ONECLICK.exe as a system user, which gives it access to Ctrl-Alt-Del & REBOOT. The batch bypasses the process for NT 4.0 and Win9x as the required programs are not present.
Just put this Run.bat in the same directory as your singleclick.exe and run it.
**Note:Use this to test it on your system to prove that it works. This won't have much real world use unless you use the version I posted down below (one that goes inside the 7zip.sfx.exe)
**REMOVED ....exe verison comming
Let me know what you guys think...

I am happy just to have Ctrl-Alt-Del as I use that quite a bit in remote trouble shooting (process kill etc)
