Probably Windows 10
It looks like this computer is running Windows 10.
Your browser doesn't share enough for us to be certain. The check below will confirm it in about 20 seconds.
Paid extended updates

Those updates end on October 13, 2026 unless your organization renews for a second year, at double the first year's price. Home PCs can't renew at all. Either way, the replacement conversation is due now.
Long-term edition
This computer is still receiving Windows 10 updates.
Its build number shows updates after October 2025, which on this build means a long-term servicing (LTSC) edition of Windows 10. Those are usually found on specialized equipment and follow their own support dates. It's worth asking your IT provider when this one's support ends.
Older version
This computer is on an older version of Windows 10.
Microsoft still updates this version only in its long-term servicing (LTSC) editions, which are usually found on specialized equipment. If this is an ordinary office PC then, as far as we can tell, it isn't getting security updates. Your IT provider can confirm in a minute.
No security updates
This computer is running Windows 10 and, as far as we can tell, hasn't received a security update since October 2025.
Its build number ends in . Updates after 6466 go only to PCs enrolled in Microsoft's paid Extended Security Updates.

19045.6456. - Type that number here.
Prefer to read it yourself?
| OS build | What it means |
|---|---|
| 26200 or higher | Windows 11, version 25H2 or newer: supported |
| 26100 | Windows 11 24H2: Home and Pro support until October 13, 2026 |
| 22631 | Windows 11 23H2: Home and Pro support ended November 11, 2025 |
| 22621 or 22000 | Windows 11 22H2 or 21H2: unsupported on every edition |
| 19045.6466 or lower | Windows 10 with no security updates since October 2025 |
| 19045, above .6466 | Windows 10 with paid Extended Security Updates |
| Any other 1xxxx number | An older Windows 10 version, almost always unsupported |
Option 2: look at Windows Update
Open Settings > Update & Security > Windows Update and read the message near the top.
What does it say?
If the buttons don't open anything, use the Start menu: Start > Settings > System > About. It works the same without them.
What changed, in plain terms
Free updates ended
Microsoft's last free security update for Windows 10 shipped in October 2025. The PC still works; it just stops getting fixes for newly discovered flaws.
Paid updates are temporary
Extended Security Updates buy time, not a fix. The consumer program and the first business year both end October 13, 2026; businesses can renew for up to two more years, at a price that doubles each year.
The real fix is a plan
Most Windows 10 PCs can either move to Windows 11 or need replacing. Knowing which of your computers are which is the first step, and it's a short conversation.
Windows 10 end of support: common questions
Is Windows 10 still supported?
Not for most computers. Microsoft ended free support for Windows 10 on October 14, 2025. Since then, security updates have gone only to PCs enrolled in the paid Extended Security Updates (ESU) program and to long-term servicing (LTSC) editions, which are mostly found on specialized equipment.
How do I check if my computer is still getting Windows security updates?
Open Settings > System > About and find "OS build" under Windows specifications. On Windows 10 version 22H2 it starts with 19045. If the number after the dot is 6466 or lower, the PC has not installed a security update since October 2025. A higher number means it is enrolled in Extended Security Updates. Builds of 22000 and up are Windows 11, where the build identifies the version: 26200 is 25H2, 26100 is 24H2 and 22631 is 23H2. The check at the top of this page does the comparison for you.
What are Windows 10 Extended Security Updates (ESU)?
ESU is a paid, temporary program that keeps critical security fixes coming to Windows 10 version 22H2. Businesses buy it per device per year: $61 for the first year, with the price doubling each year for up to three years. The first business year and the one-year consumer program both end on October 13, 2026.
Is it safe to keep using Windows 10 without security updates?
The computer keeps working, but every flaw Microsoft has fixed since October 2025 stays open on it, including flaws attackers are already exploiting. For a business it can also cause problems with cyber insurance applications and with compliance frameworks such as HIPAA, which expect systems to be supported and patched.
Is my version of Windows 11 still supported?
It depends on the version, and older versions quietly drop out of support. Version 25H2 (build 26200) is supported on Home and Pro until October 12, 2027. Version 24H2 (build 26100) loses Home and Pro support on October 13, 2026, and 23H2 (build 22631) lost it on November 11, 2025; Enterprise and Education editions get about a year longer. Versions 22H2 and 21H2 are unsupported on every edition. Updating to the latest version through Windows Update is free.
Can my computer upgrade to Windows 11?
Many can, for free. Windows 11 needs a supported processor (roughly 2018 or newer), TPM 2.0 and Secure Boot. Settings > Update & Security > Windows Update will usually say whether the PC qualifies. Machines that do not qualify generally need replacing.
Does this check install anything or collect my information?
No. It reads only the version details your browser already shares with every website, and the build number you type never leaves the page. Nothing is downloaded, installed or stored about you.
What should a business do about computers still running Windows 10?
Start with a list of which computers still run Windows 10, then decide which can upgrade to Windows 11 and which need replacing, and use Extended Security Updates only to cover the gap. An IT provider can usually pull that list from their management tools quickly. If you do not have one, ROI Technology helps businesses in Snohomish and King County with exactly this.
What to do next
Contact your IT provider and ask them to confirm which computers still run Windows 10 and how they'll be replaced. If you don't have an IT provider, we're a Snohomish County IT company and we do this every week.

A word of caution first: don't make a habit of pasting commands from websites into PowerShell, including this one. Read what a command does before you run it. Everything below is read-only and runs as a standard user.
OS build and revision
