Keeping computers on a network up to date
This article contains information to help you manage updates across a network and to find the right updates for each computer on a network. Every computer on a network needs updates that are designed for the version of Windows that it's running. A computer running Windows XP, for example, doesn't need the same updates as a computer that is running this version of Windows.
Update computers on a home network
The easiest way to keep a home network up to date is to turn on Windows automatic updating on each computer. Use the recommended setting so that no matter who uses the computer, Windows can check for updates and install them on a regular schedule. For more information, see Understanding Windows automatic updating.
Manage updates for computers on an office network
If you are a system administrator for a network, you can use these options to help keep all computers on the network up to date.
Make sure Windows automatic updating is turned on to the setting that you want all computers on the network to use. To manage the Windows automatic updating setting for each computer, use Group Policy settings for the Windows Update service.
To find updates for multiple versions of Windows, search the Windows Update Catalog online.
