Hi fade2gray, welcome to NST.
This isn't actually an issue with digital certificates (despite the evidence that might lead one to believe otherwise). The problem is that Vista doesn't allow apps that require admin elevation to run at startup.
We weren't originally planning on working around this, seeing as MS declares it to be "by design" and "intended behavior."
However, thanks to a host of people asking us to re-think that decision
, we've developed a version of iReboot that bypasses all the UAC prompts and can run at startup without any nags or problems.
You can download it here: [Download] UAC-Free iReboot BETA - The NeoSmart Forums
It's currently in the very last stages of beta development, and should be released to the general public *real* soon.
Please try it and let us know how it goes!
Have a nice day....
