问题
I was wondering if it is possible for a program to prompt the user with a UAC prompt to raise it's own privileges without starting another process.
All the examples I can find on the internet seem to ShellExecute "runas" which creates a new process with elevated privileges.
If this is not possible then my best solution I guess would be create a named pipe, ShellExecute my own program with a special argument, and then shove all the data that it will need to perform the operation down the pipe. If there are any better suggestions then this I would be glad to hear them.
Thanks for any input.

No, you can't elevate an existing process. You're right - you have start a new elevated process and get that to do the work for you.

One other possible answer (which ends up being essentially the same answer) is to have a service which runs as LocalSystem that does the elevated work for you.
