What is Runas? It is a command which is useful on Windows OS. If you use this command, it will be able to permit one to run a command in the context of another user account. Let’s take an example of the usage of it.
Let’s say that you have a normal user account and also an administrator account on a computer. And now, you are logged in as a normal user account. However, you want to install some software on the computer but because you do not have admin privileges, so you are not able to do that.
But, you will be able to do that if you use Runas command. With Runas, you just have to launch the installer from the command prompt and by providing administrator login id and password.

Let’s take an example. If you want to open registry editor as administrator of the computer, the command will be like this:
runas /user:administrator regedit
If you have run the command above, then you will be asked to insert the password of the administrator account. After the validation of the password, the registry editor will be opened with the administrator account credentials.
Now, how to specify arguments to the program? In case you wish to provide arguments to the programs that must be invoked as another user, you are able to put the name of the program and also the parameters in the double quotes.
What command do we can use if we have a lot of commands to be executed with administrator credentials? If you have a lot of commands that must be executed with administrator credentials, you do not have to run each command using runas.
You are able to open the command prompt window once as the administrator and then you are able to run all the commands in that window. So, here is the command that you are able to use for opening a command window using runas.
Runas /user:administrator cmd
And here are the examples:

Now, how about running a batch file as administrator? In case you wish to run a batch file as administrator of the computer, you will need to mention the path of the batch file in the place of command in the syntax of runas. Let’s take an example.

One of the problems may be found by people is that when they use the runas command, they get an error which says that this program is blocked by group policy. In addition, in that error message, it is also written that for more information we are able to contact our system administrator. If we find this issue, how to fix it? Are there any ways that we can do to try to fix this issue?
Well, in case you find this kind of issue, the administrator of your system may have disabled users to login from command prompt. In the group policy editor, the setting is able to be found in the node below.
Computer Configuration -> Windows Settings -> Security settings -> Local Policies -> User rights assignments
In the path above, you have to find the setting which says Deny Logon As A Batch Job. In case you have administrator privileges, you are able to disable this settings. Or, you have to contact the system or domain administrator.
