We all know the feeling—you're in the middle of a task on your device, and a notification pops up, "A new update is available." It's tempting to hit "Remind me later" and carry on with what you were doing. But here's the thing: those updates are more than annoying interruptions. They're essential protective measures for your digital life.
Why are updates so important?
- Updates Patch Security Vulnerabilities: Security updates fix vulnerabilities in software. When you install them, you're closing off known potential entry points for hackers. CISA recommends keeping software updated to fix security risks.
- Updates Enhance Functionality: Updates often come with improvements to software performance and new features. Apple's update guidance, for example, describes features, security updates, and bug fixes delivered through software releases.
- Updates Can Help Maintain Compatibility: Software and apps are designed to work together, and keeping them supported and up to date can help them continue working together. But updates don't guarantee compatibility: new versions can have known issues, too. Follow the manufacturer's guidance rather than forcing an upgrade that has been blocked for your device. Microsoft's safeguard holds, for example, prevent affected devices from receiving certain feature updates until known issues are resolved.
Actionable Steps
- Turn On Automatic Updates: Enable automatic updates wherever they're available. Check that installation—not just downloading—is enabled if your device offers separate options. Apple's instructions illustrate the distinction between automatic downloading and installation.
- Regularly Check for Updates: Even with automatic updates turned on, it's worth manually checking for updates periodically. Pay attention to notifications, and install security updates promptly—especially critical ones. CISA notes that not every update can be automatic.
- Don't Forget About Your Smaller Devices: It's easy to remember to update your computer or smartphone, but what about your smart TV, home security system, or other Internet of Things (IoT) devices? Check for firmware updates, too. Also check how long the manufacturer will provide updates; if that information isn't available, ask. Devices can become insecure when support ends. The FTC explains how to investigate a device's support period and why the end of updates matters.
- Be Patient: Updates can take time, but the security benefits are worth making time for. Follow your device's installation instructions and complete any required restart. For example, Apple recommends backing up your iPhone or iPad and connecting it to power and Wi-Fi before updating.
Key Takeaways
- Security updates patch vulnerabilities; other updates can enhance functionality and help maintain compatibility, though compatibility isn't guaranteed.
- Enable automatic installation where possible, check for updates regularly, and install security updates promptly.
- Don't neglect smaller devices like IoT devices—or their manufacturers' support periods.
- Be patient during updates—they're worth making time for.
