How to update your software
Keeping your software up to date is a crucial practice in Internet safety. Most software updates automatically by default, but you should know how to check the updates and begin the process yourself. Knowing how to keep your software updated can improve your computer's stability and security and let you know about new features, helping you be an informed and empowered user.
Update your operating system
Keeping your operating system updated is one of the most important steps in protecting yourself from viruses, malware, and other Internet security threats.
Windows
To update Windows, first open the Control Panel (or Settings app in Windows 10/11). If you don't know where the Control Panel is, check out this lesson in Windows Basics. In the search bar in the Control Panel, type update. Under Windows Update, click Check for updates.
It may take a moment for Windows to search for updates. Once it does, if there are any updates available it will prompt you to install them.
It may take a while to install all the updates. It's safe to leave the computer and do something else while it finishes. Once it's done, Windows will probably prompt you to restart the computer. If you need to do anything else after this, Windows will prompt you; otherwise, you're up to date!
macOS
To update macOS, open the App Store (or System Preferences > Software Update in newer macOS versions), then click Updates at the top. macOS updates will be at the top of the list of available updates. On the right side of the screen, there are buttons to update individual apps or to apply all available updates.
Update your apps
For many apps, regular updates provide new features and stability rather than security patches, so it isn't necessary to update them as frequently. However, for more essential software like web browsers and antivirus software, security updates are just as critical as operating system updates.
Many apps in both macOS and Windows will automatically check for updates when you open them. If you installed them through the App Store or another distribution platform, the program will alert you about updates. For standalone programs, take time to explore the program's menus and learn how to run the update process.
For example, in Avast! Free Antivirus, there is an Update page on the Settings screen.
However, in Firefox, the About Firefox screen in the Help menu also checks for updates.
FAQs
Why is it important to update my operating system?
Updating your operating system (like Windows or macOS) is the primary way to receive critical security patches that protect your computer from new viruses, malware, and hackers. It also fixes bugs and improves overall performance.
What happens if I ignore software updates?
Ignoring updates leaves known security holes open on your computer, making it easier for cybercriminals to gain access. Furthermore, older versions of software may become incompatible with new files or stop working entirely over time.
Do I have to pay for Windows or macOS updates?
No. Routine updates and security patches for modern operating systems like Windows 10, Windows 11, and macOS are provided for free by Microsoft and Apple, respectively.
Why does my computer restart during an update?
Many updates involve replacing core system files that are currently in use while the computer is running. Restarting allows the system to shut down, safely replace those critical files, and boot back up with the new versions.
Should I enable automatic updates?
Yes. Enabling automatic updates is highly recommended for average users. It ensures you receive critical security patches immediately in the background without needing to remember to check for them manually.
