WSUS Offline Update – Microsoft Patches Without an Internet Connection
WSUS Offline Generator
WSUS Offline Update allows you to update Windows Operating System software (XP, Vista, Windows 7, etc.) along with Microsoft Office products without an internet connection. It does this by downloading all of the available patches and putting them into an ISO image that you can burn and take with you. This is particularly useful when trying to patch computers that have no internet connection or on systems with extremely slow internet connectivity. It could also be used to ensure that a system is fully patched prior to connecting it to a network to help prevent virus infection and security breaches.
