Key Takeaways
The Update Habit Most People Get Wrong
The notification appears. You dismiss it. You'll get to it later. For millions of people, this is a daily ritual — and it's one of the most consequential digital habits most never examine closely.
Software updates are frequently misunderstood as a maintenance chore, something to do when convenient rather than a core part of how your device stays secure. That framing has real consequences. The gap between "an update is available" and "the update is installed" is exactly the window attackers look for.
The myths around updates are persistent and plausible-sounding. Below, we address the most common ones directly.
Myth
Software updates are mainly just bug fixes — nothing that affects me personally.
Fact
Most updates include security patches that close vulnerabilities attackers can use to access your data, accounts, or device.
The "bug fix" framing is misleading. While updates do address software errors, security patches are often the most urgent component. When a vulnerability is discovered, developers race to release a fix — but once that patch is public, the underlying flaw becomes widely known. Attackers reverse-engineer patches to identify exactly what was broken, then target users who haven't yet updated. Treating security updates as optional housekeeping misunderstands how that threat cycle works.
Myth
If my device is working fine, there's no reason to update.
Fact
A device can function normally while still being actively exploited through an unpatched vulnerability.
Many attacks are designed to be invisible. Malware that harvests credentials, monitors activity, or uses your device as part of a larger network often leaves no obvious symptoms. "Working fine" describes your experience of the device — not the security posture of it. Updates address threats that may have no visible effect on day-to-day performance until significant damage is done.
Updates also frequently improve performance and battery efficiency, so postponing them can mean missing out on a noticeably better experience. See habits that keep your apps running smoothly for related practices that make a real difference.
Myth
Automatic updates are risky — they might break something.
Fact
Automatic updates are thoroughly tested before release and are far safer than leaving devices unpatched for extended periods.
The concern about updates "breaking things" is understandable — high-profile update issues do occasionally make headlines. But those cases are rare relative to the volume of updates released, and manufacturers typically resolve significant issues quickly. By contrast, the risk of exploitation on an unpatched device is continuous and well-documented. For most users on most devices, enabling automatic updates is the right default. If you manage specialized software with known compatibility constraints, a staged approach may make sense — but that's the exception, not the rule.
Myth
Only computers need to be updated — my phone is probably fine.
Fact
Smartphones are high-value targets and require the same disciplined update habits as any other connected device.
Phones contain more sensitive personal data than most computers — financial apps, messages, location history, biometric data, stored passwords. They're also connected to networks continuously, making them an attractive and accessible target. Both iOS and Android release regular security patches, and app updates frequently address vulnerabilities in the apps themselves. Your phone's built-in apps are also regularly updated with new capabilities you may be missing by staying on older versions.
Myth
Updating apps isn't as important as updating the operating system.
Fact
Apps can contain serious vulnerabilities independently of the operating system, and outdated apps are a common attack vector.
Your operating system and your apps are separate layers of software, each with their own security posture. A fully updated operating system won't protect you from a vulnerability in an outdated browser, messaging app, or email client. Attackers frequently target popular apps specifically because many users delay app updates. Keeping both layers current — OS and apps — is the complete picture.

What Good Update Habits Actually Look Like
Staying current doesn't require constant attention. A few practical defaults go a long way:
- Enable automatic updates for both your operating system and your apps wherever possible. This removes the decision from your daily routine.
- Don't indefinitely postpone manual updates. If you defer, set a specific time — that same evening, over the weekend — rather than leaving it open-ended.
- Pay attention to "security update" labels. These carry more urgency than feature releases and should be prioritized if you're triaging updates.
- Know your device's support status. If your phone or computer is no longer receiving security updates from the manufacturer, that's important information for how you use it.
End-of-Support Devices Carry Ongoing Risk
When a manufacturer stops issuing updates for a device or operating system, known security flaws go permanently unpatched. Continuing to use an unsupported device for sensitive tasks — banking, email, shopping — carries real risk that no amount of cautious behavior can fully offset. If your device no longer receives security updates, it's worth evaluating whether it's still appropriate for those activities.
Being thoughtful about public Wi-Fi risks and keeping software updated work together — neither alone is sufficient for strong digital safety. For a broader foundation, the Online Safety hub covers the most important practices in one place.
Unpatched Devices Are Active Targets
Cybercriminals routinely scan for devices running outdated software because known vulnerabilities are publicly documented after patches are released. Waiting even a few days to install a security update can expose your device during that window. If your device still receives updates, installing them promptly is one of the highest-impact steps you can take for your digital safety.
