Run a Program as Different User

by
Running a Program as different user is one of the easiest way to impersonate a Program/Application with some other user’s privilege. For every administrators, this would be the common need either for testing or to impersonate different user privilege. In this article, I am going to write and explain about how to Run a Program as Different User and how to Run a Program as System account.

Summary

Run a Program as Different User

You can execute a program under a different user account by using the command line tool RunAs. Use the below command to open new CMD window under different user

C:> RunAs /user:rtest cmd
Run program under Different User

You will prompted to enter password when you execute this command. type password and click ‘Enter’ to open new cmd window under the different user ‘rtest’.

Run a Program as System Account

You can execute or run a program under local system account by using sysinternals‘s Psexec utility. you can download at

C:PSTools> PsExec -s cmd.exe

C:Windowssystem32>whoami
nt authoritysystem

C:Windowssystem32>exit
cmd.exe exited on HP-PC with error code 0.
Run as Local System Account

Once you have completed the work you can revert to current user by executing exit command.

Run a Program as Different Domain User for Remote Connections

You can execute a program under different domain user for remote connections by using the parameter /netonly in RunAs command. Use the below command to open new CMD window under different domain user

RunAs /netonly  /user:work2008RDtest cmd
Run as Different Domain User for Remote Connections

When you start a program with RunAs /netonly, the program will execute on your local computer as the user you are currently logged on as, but any connections to other computers on the network will be made using the user account specified.
