The only way to run a program that requires administrative access (elevation) is to use
Run as administrator (either by right-clicking or or the shell
runas verb in a script). You can also schedule the program to run with highest privileges, but doing so requires administrative permissions already and thus does not constitute bypassing the UAC prompt.
The runas command starts a program with alternate credentials, but the program is not started as administrator (elevated). In other words, you cannot use the
runas command to bypass the UAC prompt either.
You cannot use the
PsExec utility to bypass the UAC prompt either, because it installs a driver and thus must be run elevated to begin with.
Disabling UAC is not recommended for the reasons stated in the FAQ.
