The laptop on the kitchen table still turns on, still opens email, still plays videos. It is seven years old and it works fine, so why replace it? That is the exact question I get from parents, from neighbors, and honestly from myself every couple of years.
Here is the honest answer: “works fine” and “safe to use” are two different things. A device can hum along smoothly while quietly losing the security updates that keep attackers out. Below are the questions people actually ask, with straight answers.
Key takeaways
- A device becomes risky when the maker stops shipping security updates, not when it feels slow.
- Check your phone or computer’s support end date, then compare it to today.
- An unsupported device is safest for low-stakes tasks and dangerous for banking, email, and shopping.
- You can stretch an old device’s life with a few habits, but eventually replacement is the only real fix.
When does an old device actually become unsafe?
The turning point is the day the manufacturer stops releasing security patches. Up to that day, known holes get fixed. After it, newly discovered flaws stay open forever.
Think of updates as a repair crew that patches the locks on your house every month. The moment the crew retires, every new lock-picking trick works on your doors, and nobody comes to fix them. The device is not broken. It is just undefended.
This is why the update question sits at the center of device safety. If you want the reasoning in plain terms, the guide on why software updates keep you safe covers exactly what those patches do.
How do I find out if my device is still supported?
Every major maker publishes an end-of-support date. You do not have to guess.
For phones
iPhones usually get five to six years of updates from release. Open Settings, General, About, and check the model, then look up its support status. Android support varies more, but Settings, About phone, and the Android version tell you where you stand.
For computers
Windows 10 reaches its official end of support in October 2025, which means machines stuck on it are now living on borrowed time. Microsoft lists lifecycle dates on its support site. Macs typically get security fixes for roughly the three most recent macOS versions.
“End of support” is not the same as “stops working.” Your device keeps running. It simply stops receiving the monthly security fixes, and that gap widens every month afterward.
Can I keep using an unsupported device if I am careful?
For some tasks, yes. It comes down to what you do on it.
| Use of the device | Risk on an unsupported device | Verdict |
|---|---|---|
| Online banking and shopping | High: your money and card details are exposed | Stop |
| Email and password logins | High: one breach can open the door to other accounts | Stop |
| Web browsing on random sites | Medium to high: malicious pages target old browsers | Avoid |
| Streaming video, playing offline games | Low: little sensitive data involved | Fine for now |
| A kitchen photo frame or music player | Very low | Fine |
The pattern is simple. An old device is a decent media player and a poor bank branch. Retire the risky tasks to a supported phone or laptop, and let the old one handle the harmless stuff.
What can I do to stay safer while I still use it?
A few habits shrink the danger without spending a cent. None of them make an unsupported device truly current, but together they buy time.
Install every update the device will still accept, right up to the last one offered. Use a browser that still gets its own updates, since browser makers sometimes support the software longer than the operating system does. Keeping the rest of your programs current matters too, and the routine for that is covered in the guide on how to keep your software updated automatically.
Move your most sensitive accounts, like banking and primary email, onto a device you know is still supported. Even if the old machine gets compromised, the accounts that matter most are not sitting on it.
Does an old device still need antivirus?
An unsupported system is exactly where extra protection earns its keep, because the built-in defenses stop improving. Whether you need a separate product depends on the system, and the piece on whether you still need antivirus in 2026 lays out the trade-offs.
How do I know it is finally time to replace it?
Watch for a handful of clear signals. When two or three of these are true, the device has moved from “aging” to “liability.”
The maker has published an end-of-support date that has already passed. Your browser warns that it can no longer update. Apps you rely on refuse to install or start crashing. The battery on a phone or laptop no longer holds a useful charge.
When you do replace it, do not just toss the old one in a drawer with your data still on it. Erasing it properly before it leaves your hands is its own short project, and a clean wipe protects you long after the device is gone. The broader roadmap for keeping your gear safe lives in the overview of securing your phone and computer.
Here is a simple rule of thumb. If a phone or laptop stopped getting security updates more than two years ago, careful habits alone will not fully close the gap. Keep using it for low-risk tasks like music or recipes, but move banking and email to a device that still gets patches.
Your afternoon checklist
- Look up your device model and find its official end-of-support date.
- Install every remaining update the device will accept.
- Move banking, email, and shopping onto a device that is still supported.
- Switch to a browser that still receives its own updates.
- Decide which harmless tasks the old device can safely keep doing.
- Note any warning signs, like apps that will not install or a browser that cannot update.
- Set a rough replacement date so the decision does not drift for another year.
An old device is not a villain. It is a tool that has quietly slipped past its safe-use date, and once you know where that line sits, you can use it on your terms instead of hoping for the best.
