You can start another process with elevated permissions, using the runas verb when starting the process.

Something like this:

ProcessStartInfo info = new ProcessStartInfo("pathtoyourexecutable.exe");
info.Verb = "runas";
Process process = new Process();
process.StartInfo = info;
process.Start();

I don't think there is any way to get out of needing to create a new process, it can't be done at the Thread level. You could use Out-of-Process COM objects, but that's even more trouble.
