To use DevManView automatically you will have to turn off UAC. There is a way to turn it off for one application only. Microsoft released a KB on how to do it and then withdrew it. This page goes over the details:

I have not tried it. There is also an application that turns off UAC for selected applications called UAC Trust Shortcut. I have not used it either.
