A software update is a patch or upgrade to an existing piece of software that fixes issues or improves its functionality. These updates are often delivered by the original software publisher free of charge. Updates are especially critical for security-related functions and are an important part of any computer or mobile device’s security strategy.
A software system can be updated either manually or automatically. Most devices allow users to choose whether they want to be automatically notified and/or automatically download available updates. In a business setting, administrators may use a patch management or software deployment solution to push out updates and patches to all devices in a network.
Most computer and mobile operating systems (OS) include an update function that checks for and installs available patches and upgrades. These updates fix security flaws, improve overall system performance, or both. For example, Windows OS updates often include security patching as well as code that reduces memory usage and speeds up the system.
When a user checks for updates on a Windows OS-based computer, the system will scan for available patches and then display them in a list on screen. Users can select the ones they want to install and follow any instructions displayed on screen. In most cases, the computer will restart after installing updates to complete the process.
The ability to update software is crucial to improving cyber security because hackers are constantly finding new ways to break through what were once considered secure protocols. Updating software helps close these gaps and reduces the likelihood of cybercrime, including identity theft and ransomware.
