[www.yourforum.gr]

There isn¢t an easy way to set the category of an Unidentified network in Windows 7/WS2K8R2. By default, an Unidentified network will be set to Public for security. Often, the Unidentified network is setup intentionally (e.g. two machines connected via a hub; a network TV tuner, etc.). In these cases, Home/Work is a better category to allow common network tasks to succeed. Use this PowerShell script from

You must connect to the ¡Unidentified network¢ prior to running this script.
