What is a service pack?  

How do users without an Internet connection obtain updates?

Many software makers provide free downloadable updates, sometimes called a service pack, to users who have registered and/or activated their software. With operating systems, the automatic update feature can be configured to alert users when an update is available or to download and install the update automatically. Users without an Internet connection usually can order the updates on an optical disc for a minimal shipping fee.

Software manufacturers recommend you download and install all available updates when they become available. In most cases, you have the choice either to allow the software to update automatically or to assess and then decide whether to install each update individually. The automatic update option occasionally has caused problems. In one case, people preparing their income tax returns were unable to print forms when Microsoft issued an automatic update one week before the filing deadline. In another situation, an automatic update was installed on all computers — even those with this feature disabled. Microsoft claimed that the update was harmless and was for the benefit of its customers. Only later did some users realize that this secret update caused serious problems. One problem, ironically, was that updates no longer could be installed on the affected computers. Customers were furious about the issues, especially because Microsoft made the changes without informing the computer owners. One consequence of the ensuing outrage was that many people turned off the automatic update feature, fearing that future updates might cause even more damage.
