Knowing how to turn on auto update is one of the simplest things you can do to keep your device secure — yet it’s one of the most commonly disabled settings, often by accident during setup or after a “just this once” turn-off that never got reversed. Missed updates mean missed security patches, and security patches are exactly what stand between your device and the latest exploits.
If you previously turned updates off using our auto-update guide and now want them back on — or you’re just checking a new device — here’s exactly where to look on Windows, Android, and iPhone.
How to Turn On Auto Update on Windows 11
- Open Settings (Windows key + I).
- Go to Windows Update in the left sidebar.
- Click Advanced options.
- Make sure Get the latest updates as soon as they’re available is toggled on.
- Scroll down and confirm Automatic is selected under “Update notifications,” rather than “Notify to schedule restart.”
For apps from the Microsoft Store, open the Microsoft Store app → click your profile icon → App settings → toggle App updates to on.
How to Turn On Auto Update on Android
- Open the Google Play Store app.
- Tap your profile icon in the top right.
- Go to Settings → Network preferences → Auto-update apps.
- Choose Over any network (recommended if you’re not worried about mobile data) or Over Wi-Fi only.
For the Android system itself:
- Open Settings → System → Software update.
- Tap Auto-update or Download updates automatically (naming varies slightly by manufacturer) and switch it on.
How to Turn On Auto Update on iPhone
- Open Settings → tap your name at the top → App Store.
- Under Automatic Downloads, toggle App Updates on.
- For the operating system, go to Settings → General → Software Update → Automatic Updates.
- Turn on both Download iOS updates and Install iOS updates.
Why You Should Leave Auto Update On
- Security patches arrive immediately instead of sitting unapplied for weeks.
- Fewer manual interruptions — updates install overnight instead of demanding attention mid-task.
- App compatibility stays current, reducing crashes caused by outdated app versions talking to updated servers.
The main trade-off is losing control over when an update happens, which is why some people turn it off during work trips or presentations. If that’s your concern, scheduling updates for overnight hours (available in both Windows and Android update settings) gives you the security benefit without the disruption.
Frequently Asked Questions
Will turning on auto update use a lot of mobile data? Only if you choose “over any network” instead of “Wi-Fi only.” Most people set updates to Wi-Fi only to avoid using cellular data.
Can I turn auto update back off later if I change my mind? Yes — the same settings menus let you toggle it off again at any time. See our guide to turning off auto update for those steps.
Does auto update install updates immediately or overnight? On most devices, updates download automatically but install during idle time or overnight, based on your device’s official update scheduling settings.
