You can manage and monitor the status of the other PCs in your OneCare Circle of Protection from a hub computer, and take high-priority actions. You cannot perform low-priority actions, such as remotely installing Microsoft Windows updates, from a hub computer.

Because a hub computer must be connected to the Internet to remain up to date and to monitor the other computers in your OneCare Circle, it is recommended that you only make a computer a hub computer if it is frequently connected to the Internet.

To make a PC your hub computer, follow these steps:

1. Open OneCare.
2. Click Manage Your OneCare Circle.
3. Click Make this PC a hub PC.
4. Enter the Windows Live ID that you used to install OneCare, and then click Sign in.

To perform a remote action from a hub computer, follow these steps:

1. Open OneCare.
2. Click Your OneCare Circle.
3. Examine the Actions to take notices for the computers that are listed as part of your OneCare Circle. Under the name of the PC that you want to perform an action on, in the Actions to take notice, click the appropriate button.
