RunAsUser

Any Windows application that is launched on your PC is executed under the account of the logged in user. Furthermore, you can execute it with administrative privileges if you want to. But with RunAsUser, it is possible to launch a program in Windows under a different user account.  
There is no standard user interface for RunAsUser, as it only runs in the command console. Nevertheless, the syntax is pretty simple and, provided you have a look at the application’s manual in the INFO.txt file, you should not have issues with it.

Specifiy the user, the password and the command  

The RunAsUser executable file accepts the following parameters: the user's name, the password and the command to execute as the specified user. The account can either be local or one from a domain controller. In the latter case, you must use the following format: “DOMAIN/username”.
RunAsUser requires you to provide the correct user password, even if empty. The ScramblePwd tool is included in the package, allowing you to generate scrambled passwords for your user accounts. Please keep in mind that scrambling a password does not necessarily mean that the original key cannot be recovered through reverse engineering.
Last but not least, the “cmd” parameter specifies the command or the application to execute using the chosen user account. This includes a Windows executable which, in turn, accepts its own command line parameters.
RunAsUser displays the 0 exit code if successful and automatically generates a report in the Windows event log, a report that includes all the technical information and the details you need.

Executes a command under a specific user account 

With RunAsUser, you can launch a program under a different Windows user account. While the application is rather easy to use, some might find it difficult to work with the command console. On the other hand, such an application can be integrated in other development projects with ease.
