Steel RunAs has you covered.

Steel RunAs helps you in executing commands or applications which run properly when run only with administrator privileges without having to give the user full rights to his machine.

Steel RunAs outputs a single executable (“.exe”) and does not need any installation in the target machine. Steel RunAs also doesn’t need any extension through command line. The end user can simply double click to execute the destined program with alternate credentials.

Strong encryption standards keep the embeded credentials safe and secure.
