A version's build number never changes; the revision after the dot rises with each cumulative update. Version 1607 shares build 14393 with Windows Server 2016, and 1809 shares build 17763 with Windows Server 2019. 1809 was first released on 2018-10-02 and re-released on 2018-11-13.

LTSB and LTSC editions

Extended Security Updates (ESU)

ESU gives eligible Windows 10 22H2 PCs critical and important security updates after end of support. It does not include feature updates, other fixes or technical support.

  • Consumer ESU (Home, Pro, Pro Education, Pro for Workstations) runs through 2027-10-12. Microsoft extended it on 2026-06-25; the original end date was 2026-10-13, which some older pages and articles still show.
  • Ways to enroll: sync your PC settings to a Microsoft account (no cost), redeem 1,000 Microsoft Rewards points, or pay a one-time $30 USD. One license covers up to 10 devices.
  • To enroll: open Settings, Update & Security, Windows Update and select Enroll now. The device must run 22H2 with the latest updates, and you need an administrator Microsoft account.
  • Not eligible: devices in kiosk mode, and devices joined to Active Directory or Microsoft Entra ID or managed by MDM.
  • Organizations buy ESU in yearly terms that end 2026-10-13, 2027-10-12 and 2028-10-10.

Find your version from a build number

Enter the number from winver or Settings, for example 19045.7727, or just a version such as 1909.

Type a build number such as 19045.7727, or a version such as 22H2.

How to check which version you have

  • Press Win+R, type winver and press Enter. The window shows the version and OS build.
  • Or open Settings, System, About and look under Windows specifications.
  • In Command Prompt, ver prints something like Microsoft Windows [Version 10.0.19045.7727]. The five digits after 10.0. are the build, and the number after the dot is the revision.

In PowerShell, this prints the version, build and revision in one line:

$v = Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion'
'{0} (build {1}.{2})' -f $v.DisplayVersion, $v.CurrentBuildNumber, $v.UBR

DisplayVersion exists on 20H2 and later. On 1909 and earlier, read ReleaseId instead.

Frequently asked questions

Is Windows 10 still supported?

Not for Home, Pro, Enterprise or Education. Support for 22H2, the last version, ended on 2025-10-14. Security updates still arrive for PCs enrolled in Extended Security Updates and for the long-term servicing editions (Enterprise LTSB 2016, LTSC 2019, LTSC 2021 and IoT Enterprise).

What is the latest Windows 10 version?

22H2, build 19045. Microsoft calls it the final version of Windows 10. Builds after 22H2 keep the 19045 number and only the revision after the dot changes, for example 19045.7727.

Can I still download Windows 10?

Yes. Microsoft's Download Windows 10 page is still online and offers the Media Creation Tool and an ISO. Older versions such as 1507 to 21H2 are not offered there; Windowstan's per-version pages cover those.

What is an enablement package?

A very small update that switches on features already included in a newer version. 1909, 20H2, 21H1, 21H2 and 22H2 all arrived this way, so moving between them takes one restart.

What is the difference between LTSB and LTSC?

They are the same idea. LTSB (Long-Term Servicing Branch) was renamed LTSC (Long-Term Servicing Channel) with the 2019 release. Both skip feature updates and follow a fixed lifecycle.

Do all editions share the same build number?

Yes. Home, Pro, Enterprise and Education of one version use the same build number, such as 19045. The revision after the dot rises with each cumulative update.

Sources and updates

Versions, builds and dates come from Microsoft Learn (Windows 10 release information and the lifecycle pages) and from Microsoft Support KB articles. The consumer ESU end date comes from Microsoft's consumer ESU page. Lifecycle pages give end dates as the following day in UTC; this page shows the last day of support in Pacific time, which matches Microsoft's Patch Tuesday dates. Last checked 2026-09-20.
