That little notification pops up right as you’re about to sit down and watch something. “Restart now to install updates.” You click “remind me tomorrow” for the fourth night in a row. It’s annoying, it’s badly timed, and it always seems to want a restart at the exact wrong moment.
It’s also one of the best things you can do to keep malware off your devices, and most people ignore it anyway.
What an update is actually fixing
When a company releases a software update, it’s often patching a hole that someone found, a way in that attackers could use to run their own code on your device, steal data, or install ransomware without you clicking anything obvious. These are called vulnerabilities, and they get discovered constantly in operating systems, browsers, apps, and even the software running on your router.
Once a vulnerability becomes public, or once attackers find it on their own, it turns into a race. The company that makes the software rushes out a fix. Attackers rush to exploit the hole before people install that fix. Every device that hasn’t updated yet is still exposed, sitting there as an easy target long after a solution already exists.
This is why “I’ll get to it later” is riskier than it feels. Later isn’t neutral. Later is time an attacker gets to work with.
Why people put updates off
Nobody skips updates because they don’t care about security. They skip them because updates are disruptive at a bad time. A few real reasons this happens:
The timing is always wrong. Updates show up mid-task, mid-meeting, or mid-movie, and a restart feels like it costs more than it’s worth in the moment.
Old bad updates left scars. Somewhere in the past, an update broke something, slowed a device down, or changed a setting nobody asked for. That memory makes people cautious about every update since.
It feels optional. The device still works fine without it, so the update seems like a nice-to-have rather than something urgent.
All of that is understandable. None of it changes what’s actually happening while an update sits unapplied: a known, documented weakness stays open on your device.
Why automatic updates are worth the annoyance
Turning updates on automatically removes the decision entirely, which is the point. You’re not relying on remembering, or on finding a good time, or on reading a security bulletin to know something matters. The fix installs close to when it becomes available, and the window where you’re exposed shrinks.
A few reasons this is worth the occasional inconvenience:
It closes the gap attackers count on. Most malware doesn’t need you to make a mistake. It needs an old, unpatched version of something you already have installed. Automatic updates shrink that opportunity without you having to think about it.
It covers the software you forget about. People remember to update their phone. They forget about their router firmware, their smart TV, their smart doorbell, or apps they rarely open. If you’ve got connected devices around the house, it’s worth checking how they handle privacy and updates together, which is part of what’s covered in Smart Doorbell and Camera Privacy: What Neighbors and Guests Should Know.
It’s low effort for real protection. You don’t need to become someone who reads changelogs or follows security news. Turning on automatic updates is a five-minute setting change that keeps working in the background indefinitely.
It reduces one more decision fatigue point. Security works best when it doesn’t depend on willpower. The fewer manual security decisions you have to make correctly every single time, the safer you tend to be overall. Compare that to something like a password manager, which does the same thing for login security by removing the need to remember or reuse passwords; if you haven’t looked into one yet, What a Password Manager Actually Does, and Why It’s Worth the Switch is a good next read.
Where to turn automatic updates on
Most major platforms support this, though the setting lives in a slightly different place on each one.
- Phones (iOS and Android): Look under Settings, then General or System, for “Software Update” or “System Update,” and enable automatic installation.
- Computers (Windows and Mac): Check Windows Update settings, or System Settings on a Mac, and turn on automatic downloads and installation.
- Browsers: Most modern browsers update automatically by default, but it’s worth confirming, since browsers are one of the most common paths malware uses to reach a device.
- Apps: Both major app stores let you turn on automatic app updates so individual apps patch themselves without you checking each one manually.
- Routers and smart home devices: These get missed most often. Check the manufacturer’s app or admin page for a firmware update option, and enable automatic updates if it’s available.
If a device doesn’t support automatic updates at all, put a reminder on your calendar to check it manually every month or so. It’s not as good as automatic, but it beats never checking.
When manual checking still matters
Automatic updates handle most of the work, but they’re not a reason to stop paying attention entirely. A few situations still call for you to check things yourself:
- After buying a used or refurbished device, check that it’s running the current operating system version before you start using it for anything sensitive.
- If a device feels slow, behaves oddly, or shows unexpected pop-ups, check for pending updates as one of your first steps, not your last.
- Before a big life moment involving more screen time or new accounts, like the start of a school year, it’s worth doing a broader check of settings, not just updates. That’s a good moment to also look at Instagram and TikTok Privacy Settings Worth Checking Before School Starts.
- If you get an update notification through email or a pop-up rather than through the device’s own settings menu, be careful. Attackers sometimes disguise malware as an “urgent update” to get you to install something harmful. If anything asks you to log in or download software from a link, treat it the way you’d treat any suspicious page, and review How to Spot a Fake Login Page Before You Type Your Password before you type anything in.
A small habit that carries real weight
Automatic updates won’t stop every threat. No single setting does that, and anyone who tells you otherwise is overselling it. Phishing, scams, and social engineering can still get past a fully updated device, because they target you, not the software. But updates close off one of the easiest, most reliable paths attackers use, and they do it without asking anything of you beyond a one-time setting change and the occasional restart at an inconvenient moment.
That trade is worth taking. Turn it on once, let it run, and put your attention toward the threats that actually need it, like a suspicious job posting or an unexpected login page.
A quick safety note
This article is general information, not professional security, legal, or medical advice. No single tool or setting makes anyone completely safe; security works in layers. If you are dealing with a live incident, such as active fraud, ransomware, or a child in danger, contact the appropriate professionals or authorities. For a threat to a child, report it to the NCMEC CyberTipline at report.cybertip.org and to local law enforcement.
