Get Windows Build Numbers

Easily get build numbers for Windows 10/11 feature updates through automated means.

🤔 Why make this?

So what's one thing that can be obnoxious with updating compliance policies in Microsoft Intune? Not being able to easily update the build numbers for in-service Windows releases easily. I initially wrote a PowerShell script in late 2020/early 2021 that would get the Windows 10 feature updates, build numbers (Based on the quality updates for their respective feature updates), and their servicing support status, but it eventually got complicated to update as a single PowerShell script. I could have converted the entire thing into a pure script-based PowerShell module, but I've got other plans for using this outside of PowerShell.

As far as I'm aware, Microsoft doesn't provide a simple API or utility to get this information. It's all web-based, which makes automation harder when you need to use that data.

⚙️ How does it work?

It's very simple, but also very complicated. Data is gathered from these sources:

Windows Release Health dashboard
Microsoft's lifecycle pages:

Data is scraped from these pages using regular expressions and returned with this data:

The feature update's release name (Eg. 21H2)
The end-of-life date for both the consumer and enterprise releases and whether or not it is currently end-of-life.
A collection of all of the quality updates released for that release.
- Data returned is:
  - The build number
  - The servicing channels it has been released to.
  - The date it was released on and whether or not it's a "Patch Tuesday" release.
  - The KB article ID and it's URL.

🛒 Current availability

Right now there are two components currently available for use:

A standard class library that drives the core functionality of getting the data.
A PowerShell module for using through a command-line interface (CLI).

Nuget package

⚠️ Note

A Nuget package has not been published yet.

PowerShell Module

⚠️ Note

The PowerShell module requires PowerShell 7.2 or higher to run.

There are no plans at the moment to support Windows Powershell 5.1, which is installed on Windows 10/11 by default, due to the reliance on targetting .NET 6 and higher.

You can install the PowerShell module from the PowerShell Gallery by running the following command in a PowerShell console:

Install-Module -Name "SmallsOnline.WindowsBuildNumbers.Pwsh"

Once installed, you can run commands like so:

Example 01

Get all release info for Windows 10.

PS > Get-WindowsReleaseInfo -WindowsVersion Windows10

ReleaseName       : 22H2
ConsumerEoLDate   : 5/14/2024 10:59:59 PM -08:00
ConsumerIsEoL     : False
EnterpriseEoLDate : 5/13/2025 10:59:59 PM -08:00
EnterpriseIsEoL   : False
ReleaseBuilds     : {19045.2311, 19045.2251, 19045.2130}

ReleaseName       : 21H2
ConsumerEoLDate   : 6/13/2023 10:59:59 PM -08:00
ConsumerIsEoL     : False
EnterpriseEoLDate : 6/11/2024 10:59:59 PM -08:00
EnterpriseIsEoL   : False
ReleaseBuilds     : {19044.2311, 19044.2251, 19044.2194, 19044.2193…}

[...]

Example 02

Get all release info for Windows 11.

PS > Get-WindowsReleaseInfo -WindowsVersion Windows11

ReleaseName       : 22H2
ConsumerEoLDate   : 10/8/2024 10:59:59 PM -08:00
ConsumerIsEoL     : False
EnterpriseEoLDate : 10/14/2025 10:59:59 PM -08:00
EnterpriseIsEoL   : False
ReleaseBuilds     : {22621.900, 22621.819, 22621.755, 22621.675…}

ReleaseName       : 21H2
ConsumerEoLDate   : 10/10/2023 10:59:59 PM -08:00
ConsumerIsEoL     : False
EnterpriseEoLDate : 10/8/2024 10:59:59 PM -08:00
EnterpriseIsEoL   : False
ReleaseBuilds     : {22000.1281, 22000.1219, 22000.1165, 22000.1100…}

Example 03

Get the release info for a specific feature update release of Windows 11 and list all quality update builds for that feature update.

PS > $win11Release = Get-WindowsReleaseInfo -WindowsVersion Windows11 -ReleaseName "22H2"

PS > $win11Release

ReleaseName       : 22H2
ConsumerEoLDate   : 10/8/2024 10:59:59 PM -08:00
ConsumerIsEoL     : False
EnterpriseEoLDate : 10/14/2025 10:59:59 PM -08:00
EnterpriseIsEoL   : False
ReleaseBuilds     : {22621.900, 22621.819, 22621.755, 22621.675…}

🧮 Plans for the future

In the future, I am planning two extra pieces:

A public web API.
A public website for viewing the data.

All of which will be open-source for your own use-cases, such as self-hosting or utlizing in your own projects.

🏗️ Building from source

🧰 Pre-requistites

.NET 7 SDK
- .NET 6 is the minimum SDK version for the class library, but, in the future, the API and public website will be targeting .NET 7 and future releases as they come out.
