How do I update my operating system?
What is an update or a patch?
After the release of particular software, enhancements to the original software can be developed which often deal with situations not in existence when the software was first marketed; also flaws or unanticipated vulnerabilities can be found after release. In such circumstances, the software company often releases an update or 'patch' that fixes a particular vulnerability, or new software that addresses an unanticipated issue, or software that recognises newly developed and released hardware.
If you have a dial-up computer connection, the process of updating can be somewhat slow. Even though it may take some time, don't ignore the need to update! Go and make yourself a cup of tea, take a deep breath, and let the updates download.
If you have an older computer with Windows XP, it is important to update this operating system with the Service Pack 2 package of security enhancements. This is freely available on the Microsoft website. If you have a dial-up connection, you could ask a friend to put it onto a CD for you to download offline or you could look at some of the computer or Internet magazines, which often offer common software updates on free CDs.
Microsoft has put in place automatic processes to prove beyond reasonable doubt the authenticity of the computer making the request for updates. This check verifies the legitimacy of the operating system used by the computer system for copyright and licensing purposes.
Updates are also available online for Apple and Linux systems. These systems are usually set to automatically update by default.
Beware of email scams regarding system updates that often have a nasty payload of malware. For example, Microsoft will never send you a notice via email to update your operating system. If you are concerned that a Microsoft security related message is not genuine you can check out their security website at the following link: http://www.microsoft.com/security/incident/authenticate_mail.mspx
