Patches are software and operating system (OS) updates that address security vulnerabilities within a program or product. Software vendors may choose to release updates to fix performance bugs, as well as to provide enhanced security features. Software updates are important because they often include critical patches to security holes. They can also improve the stability of your software, and remove outdated features. All of these updates are aimed at making the user experience better.
A common operating system update is a security update, which is issued to protect your computer against vulnerabilities that might be exploited by hackers and viruses. It is wise to install security updates when they are released to ensure your system is as protected as possible against constantly changing threats
