When does my computer stop getting security updates?
Three makers, three completely different kinds of answer. Google publishes a date for every Chromebook, Microsoft publishes one for every version of Windows and none for any laptop, and Apple publishes neither. This checks yours against what the maker actually published.
What are you using?
These three are asked differently on purpose. Google publishes an end date for each Chromebook, Microsoft publishes one for each version of Windows and none for any laptop, and Apple publishes neither. Picking one first is how this page avoids giving you a confident answer built on the wrong question.
Why it asks which system you use first
Because for a Windows laptop, the answer is not a fact about the laptop. Microsoft publishes end-of-servicing dates per Windows version and has never published one per model, so a 2015 ThinkPad running 25H2 is covered until October 2027 while a 2024 machine still on 24H2 stops in October 2026. The newer computer runs out first, and nothing about the hardware predicts it.
A single box asking which computer you own would have to invent the difference between those two machines. Pages that do it anyway produce a confident date by averaging what makers did before, which is a guess wearing the same typeface as a fact. Asking the question the maker actually answers costs one extra click and is the only version of this page that is true.
What running out actually means
Nothing switches off. The computer starts the day after exactly as it did the day before, which is what makes this a hard deadline to take seriously. What changes is that newly discovered flaws stop being fixed, so the gap between what attackers know and what your machine is protected against only widens from there.
For Windows this rarely means buying anything. An expiring version is a free update away from a supported one on the same hardware, and even Windows 10 has a route that costs nothing. Replacing a working computer over a date is usually the most expensive answer to the problem, and it is the one most pages covering this moment recommend. If you are weighing that decision on a phone rather than a laptop, the repair or replace calculator does the same arithmetic, and the phone update checker covers handsets.
Frequently asked
When does Windows 11 stop getting security updates?
It depends on which version of Windows 11 you are running, not on which computer you own. Microsoft services each version for 24 months on Home, Pro, Pro Education and Pro for Workstations, and 36 months on Enterprise and Education. Version 24H2 stops receiving updates on 13 October 2026 and 25H2 on 12 October 2027. This catches people out because it means a newer laptop can run out before an older one: a 2015 machine on 25H2 is covered a year longer than a 2024 machine still on 24H2. Moving to a newer version is free and resets the clock on the same hardware. One trap worth knowing: 26H1 is a higher number than 25H2 but it is not a route off an expiring version, because Microsoft scoped it to new devices that came to market in early 2026 and does not offer it as an in-place update from 24H2 or 25H2. Press the Windows key and R, type winver and press Enter to see which version you are on.
Is Windows 10 still getting security updates?
Not by default. Windows 10 reached end of support on 14 October 2025, and version 22H2 was the final version. Microsoft's consumer Extended Security Updates programme continues to deliver critical and important security updates for devices on 22H2, and there are three ways in, of which the first is free: syncing your PC Settings, redeeming 1,000 Microsoft Rewards points, or a one-time purchase of $30 USD. It covers security updates only, with no feature improvements and no technical support.
When does Windows 10 Extended Security Updates end?
12 October 2027. This is worth stating plainly because the date most widely published is 13 October 2026, and that is now out of date. Microsoft's own consumer ESU page states the 2027 date and does not mention the 2026 one anywhere. If you read otherwise, check the date on the page you are reading, then check Microsoft's.
How long do Chromebooks get updates?
Google's policy is that ChromeOS devices receive 10 years of updates, and the crucial detail is that the ten years run from the platform release date rather than from the day you bought the machine. Two Chromebooks bought on the same afternoon can expire years apart, so the age of your laptop does not tell you the answer. Google publishes an Auto Update Expiration date for every model, which is why this is the one part of the tool that answers per device. Some models carry a condition: the longer window applies only if the device opts in to extended updates, and the checker says so where that applies rather than printing the date alone.
How long does Apple support a Mac?
Apple has never published a figure, for any Mac. What it publishes is which models can run the current macOS, currently macOS Tahoe 26, and that is a compatibility list rather than a support window. Falling off it does not mean security updates have stopped: Apple issues security updates for older macOS versions alongside the current one, so a Mac that cannot install the newest release can still be receiving patches. Anyone quoting you a confident end date for a Mac has inferred it from Apple's past behaviour, which is a reasonable thing to do and a different thing from a published commitment.
Where do these dates come from?
Manufacturer pages only. Google's Auto Update Expiration list for Chromebooks, Microsoft's Windows release-health and lifecycle tables for Windows versions, Microsoft's consumer ESU page for the Windows 10 extension, and Apple's compatibility list for the current macOS. Every date shown links to the page it was read from. Nothing here comes from a roundup, and where a maker publishes nothing the tool says so rather than filling the gap.
