PsTools : psexec to import .reg on remote PC

I'd like to use psexec in a .vbs or .bat file, where when executed, it will push, or import a .reg file into the registry of a remote machine. Luckily for me, the registry key is in the same place for all systems. The helpdesk will push the .reg key out when it is needed on a system. What I would like to have happen, is when the helpdesk folks double click the script, a pop-up will occur asking for the hostname, or PC name where the .reg file should be imported to. They then input the hostname of the remote PC, press OK or submit, or whatever, and it push to that machine. A reboot does not need to be executed at that time. Any assistance it greatly appreciated, and thank you!
