Step-by-Step: Help Protect Your
Computer with Critical Updates
August 11, 2003

Keeping your operating system current with the latest updates
from Microsoft is the most important step you can take
toward more stable and secure computing.

Updates—also known as fixes, patches, and service packs—address exploitable flaws or add new features to software. Updates that are classified as critical by the Microsoft Windows Update service improve your computer's security and compatibility. To help protect your computer and keep it running smoothly, you should install critical updates as soon they become available.

The Best Method: Automatic Updates and Installs
The latest Microsoft® Windows® operating systems—Windows XP and Windows 2000—give you the option of installing updates automatically so you stay current with important updates. The Automatic Updates feature works in the background, so it doesn't interfere with your computing. To check for and download updates, your computer simply needs to be turned on and connected to the Internet. It does the rest for you. But even if you are using an earlier version of Windows, there are still some simple steps you can take to stay informed of important updates.

From time to time malicious individuals circulate e-mails that purport to be a
Microsoft Security Bulletin or Patch. Some of the emails direct the reader to
download an executable file from a web site - while others include
an executable file which contains a virus.

Customers who receive such an email should delete it, and under
no circumstances should they download or run the executable.

Some of the emails claim to be a security patch for
Windows or Internet Explorer, others are more generic.

There are several clues which indicate that the e-mails
aren’t a bona fide security bulletin or patch:

• The e-mail isn't signed using the Microsoft Security Response Center’s digital signature. The Microsoft Security Response Center always signs its bulletins before mailing them, and you can verify the signature using the key we publish at http://www.microsoft.com/technet/security/bulletin/notify.asp. If you are ever in doubt about the authenticity of a bulletin mailer you’ve received, consult the web-hosted bulletins on the Microsoft Security web site – the versions there are the authoritative source for information on Microsoft Security Bulletins.

• The e-mail contains a patch. Authentic security bulletin mailers never provide the patch itself or a link to the patch; instead, they refer the reader to the complete version of the bulletin on our web site, which provides a link to the patch. More information on the Microsoft policy on software distribution is available at: http://microsoft.com/technet/security/policy/swdist.asp

• The "patch" contained in the bogus bulletin isn't digitally signed by Microsoft. Microsoft always digitally signs the patches it releases. Always be sure you check the signature of any executable before installing it on your system.
