Which command is used for quickly configuring WinRM?

The command used for quickly configuring Windows Remote Management (WinRM) is "winrm quickconfig." This command facilitates the swift setup and configuration of WinRM on a Windows machine, making it accessible for remote management. When executed, it performs several tasks automatically:

1. It checks whether the WinRM service is running and starts it if it is not.

2. It creates a listener to accept requests on the default ports.

3. It enables the necessary Windows Firewall exceptions for WinRM.

By streamlining these essential steps, "winrm quickconfig" greatly simplifies the setup process, especially for users who need to establish remote management capability in a timely manner. This command is particularly useful in environments where quick deployment of remote management services is necessary.

Other options provided are not the correct command for this purpose. For instance, "winrm startconfig" and "winrm setup" do not exist as valid WinRM commands, while "winrm configset" is not a standard command used for configuring WinRM quickly. The selection of "winrm quickconfig" is therefore the most effective and relevant choice for the required task.
