Why updates matter
Once a security flaw is discovered, attackers move quickly. Software vendors release fixes — but the fix only protects you if your device installs it. Automatic updates close that gap without you having to remember.
Turn on auto-updates
- cyber.gov.au — Update your devices and software
Australian government's plain-English guide — covers Windows, macOS, iOS and Android.
- Windows — Windows Update FAQ
Microsoft's detailed Q&A. Feature updates twice a year; quality updates more often.
- Apple — iOS / iPadOS / macOS
Auto-downloads and installs when charging on Wi-Fi.
- Android — Google Play and system updates
System updates depend on your manufacturer — check their site too.
If auto-updates do not work
- Open Settings and run an update check manually.
- Free up storage space — updates can fail when storage is full.
- Make sure the device is on Wi-Fi and charging.
- If a major version upgrade is offered (e.g. Windows 11, iOS 19), back up first.
End-of-support devices
Older products eventually stop receiving security updates — examples have included Windows 7 and iPhone 6. After that point, any newly discovered flaw stays open on that device. If you are still using one for banking, email or sensitive accounts, plan to upgrade to a supported device.
Update checklist
- Confirm your device can still receive the latest updates.
- Replace anything too old to be supported anymore.
- When buying a new device, run updates immediately during setup.
- Turn on automatic updates everywhere they are offered.
- Back up before installing a major OS upgrade.
- Watch storage — full disks make updates fail.
- If automatic updates are not available, set a calendar reminder to check manually.
