Have you ever wondered what a security patch is and of what use it has for you? Well, you have come to the right place! At its most basic definition, a security patch is simply computer code or a program file that is intended to correct or fix errors in a program. In previous years, applying a security patch entailed actually having to make changes to the executable by way of machine instructions. Nowadays however, most software developers simply provide a replacement .exe or .dll file, which replaces the executable module entirely. The necessary file or files are usually made available for download from the developer's site, and the user will then simply have to click on the appropriate link and apply the patch. In most cases, the security patch will be installed automatically once it has finished downloading.
While patches are often applied in order to fix a problem with the program in question, it may also be used to enhance the program, to add new features, or to implement additional functions. A security patch on the other hand is typically provided in order to increase protection against attacks by malicious software or viruses. In certain cases, the release of a security patch for certain software may mean that it is poorly coded or poorly designed. For this reason, some people tend to avoid software from companies that release patches frequently.
Microsoft is one company that releases security patches every month. The company employs a security team whose sole task is to release patches as soon as possible after a vulnerability threat is detected. One of the most prominent cases involving a Microsoft security patch pertains to a BSOD (or Blue Screen Of Death) issue in which a patch released by the company caused the familiar error. Many of the users who complained about the issue were Windows XP users, although some Windows Server 2003, Windows Vista and Windows 7 users were affected as well. At the time of this writing, no Windows 2000 and Windows Server 2008 users have reported any issues from applying the said security patch. That being said, the new Blue Screen issue is a relatively new one, and the Windows security team expects that more reports of issues may come in as more and more users apply the said security patch.
