What Is a Chromebook? And the Date You Should Check

You are weighing up a Chromebook because it is cheap, quiet and does not seem to need much looking after. That is mostly fair.

There is one date attached to every one of them that decides how long it lasts, and it is not printed on the box. It is also not counted from the day you buy it.

I counted the programs on the Windows machine this was written on, to show what the trade actually is. It came to 1,403.

What it actually is

Two paragraphs, and then the part that matters.

⭐ A Chromebook is a laptop that runs ChromeOS instead of Windows. The browser is the machine. Most of what you do happens in a tab.

⚡ It also runs Android apps from the Play Store on nearly every current model, which covers a lot of the gap.

⛔ It cannot run a Windows program. No .exe, no installer you downloaded from a software site, no desktop application that was written for Windows.

The date that decides how long it lasts

The thing to check before you spend anything.

Documented by Google on its update schedule page: "Chromebooks receive 10 years of automatic updates."

⛔ Ten years from the platform release date, not from your purchase. A model on the shelf today may be built on a platform released years ago, and the clock started then.

⚡ Google calls the end of it the Auto Update Expiration date. It is published per device. Not a general policy you can assume.

⚠️ This is the most useful thing to look up before buying. No shop display mentions it.

Checking the date, in four clicks

Google's own route, on a machine you own or one in a shop.

Google's steps, quoted: "At the bottom right, select the time and then Settings", then "At the bottom left, select About ChromeOS", then "Select Additional details", and read the Update schedule section.

⭐ That gives the final update date for that exact device. Not the range, not the model family. That one unit.

⚡ On a second-hand Chromebook this takes precedence over the price. Two years left is a very different purchase from eight.

Ours: 1,403 programs a Chromebook would not run

The measurement, and it is the whole trade in one number.

Ours, counted on the Windows PC in front of me. There were 1,403 executable files across 42 top-level program folders. I counted executables rather than installed applications, because that is what a file system can answer honestly.

⚡ Count your own if you are weighing this up. The rest of what is in your PC is read the same way, and this line only reads:

(Get-ChildItem $env:ProgramFiles -Recurse -File -Filter *.exe -Force -ErrorAction SilentlyContinue).Count

⚠️ That count is not 1,403 separate applications. One program installs many executables, and the real number of installed apps is far smaller.

⭐ The point is the shape of it. If your own count is mostly things you never open, a Chromebook loses you very little. If four of them are the reason you own a computer, it loses you everything.

⛔ Ours, and marked as ours: no Chromebook was measured here. Everything above about ChromeOS comes from Google's documentation rather than from a device on this desk, and the body does not pretend otherwise.

What it genuinely does well

Being fair, because the case for one is real.

⭐ It starts in seconds and stays that way for years. There is very little on it to accumulate.

⭐ Updates install in the background and apply on restart. No hour-long screen, no restart you have to schedule.

⚡ The security model is stronger than most people expect. Each tab and app is separated. The system checks itself at every boot.

⚠️ And a cheap Chromebook feels quicker than a cheap Windows laptop at the same money. It asks far less of the hardware.

What you give up

The list, plainly.

⛔ Windows software. Office desktop apps, most accounting and tax software, most games, anything specialist your work uses.

⛔ Serious local storage. Most models ship with 32 or 64 GB. That is a phone-sized drive.

⚠️ Peripheral support is narrower. Printers are usually fine. Scanners and older specialist hardware often are not.

⭐ And a genuinely offline life is harder. It works offline more than its reputation suggests, and it is still built around being connected.

When the date passes

What actually happens, and it is less dramatic than it sounds.

Google's own words: "If you get a 'Final software update' notification, your device won't receive ChromeOS and browser updates anymore."

⚡ It keeps working. Nothing switches off, and the machine boots the next morning exactly as before.

And Google adds: "Even if your Chromebook no longer gets automatic updates, it still comes with a verified boot. If the system is tampered with, it repairs itself."

⛔ But no browser updates means no security fixes, on a device whose whole job is the browser. That is the reason the date matters.

Who it actually suits

The recommendation, since that is what you came for.

⭐ A second machine, a child's machine, or a life lived in a browser. Those three are a clear yes.

⚠️ One computer for a whole household is a harder call. The one program somebody needs is usually the thing that decides it.

⭐ If you are replacing a slow Windows laptop, check why it is slow first. Two numbers usually explain it, and neither of them costs a new machine.

Status: written 25 August 2026 against Google's Chromebook update documentation. Google supplies the ten years of automatic updates, the route through Settings, About ChromeOS and Additional details, the Final software update notification wording and the statement about verified boot. The executable count is from the Windows PC used to write this, and no Chromebook was tested here.

How long do Chromebooks last?

Google states that Chromebooks receive 10 years of automatic updates, counted from the platform release date rather than from your purchase. That is why the same model can have eight years left or two. Check it before you buy.

How do I find my Chromebook's expiry date?

Select the time at the bottom right, then Settings, then About ChromeOS at the bottom left, then Additional details. The Update schedule section names the final update date for your exact device.

Can a Chromebook run Windows programs?

No. ChromeOS does not run .exe files or Windows installers. Most current models run Android apps from the Play Store, which covers a good deal of everyday use. A Windows desktop application will not start.

Is a Chromebook still safe after the update date?

It keeps working and Google says verified boot still repairs a tampered system. What stops is browser and ChromeOS updates, so security holes found afterwards are never patched. On a device built around the browser, that is a real limit rather than a technicality.

Is a Chromebook better than a cheap Windows laptop?

At the same low price it usually feels quicker, because it asks less of the hardware. The Windows laptop runs software the Chromebook cannot. Decide by listing the programs you actually open rather than by the specification sheet.

The Short Version

• A Chromebook runs ChromeOS, and most current models also run Android apps.
• It cannot run Windows programs at all. No .exe, no Windows installers.
• Google gives 10 years of automatic updates from the platform release date.
• That clock does not start when you buy it, which is the trap.
• Settings, About ChromeOS, Additional details shows your exact device's final update date.
• The Windows PC here held 1,403 executables across 42 program folders.
• After the expiry date it keeps working, but stops getting security updates.
• Best as a second machine, a child's machine, or for a life lived in a browser.

Where to Next

Look up the Auto Update Expiration date before you buy anything, including new stock in a shop. Four clicks on the display model gives you it.

If you already own one, check it the same way. Knowing you have two years left changes what you would spend on repairs.

Count the programs on the machine you have now. If the list is mostly things you never open, the trade is smaller than it looks.

Should you have hit something a Chromebook genuinely could not do for you, name it in the comments. Those specifics help more than a feature list.
