The file can be edited manually using a text editor or through the IIS Manager, which provides a graphical user interface for managing the settings in the file. However, it is recommended to make a backup of the file before making any changes to avoid any potential issues.

In summary, applicationHost.config is an essential configuration file for IIS that contains various settings related to the management of websites and applications hosted on the server. It should be edited with caution and a backup should be made before making any changes.
