Let’s understand Windows 10 Version Numbers and Build Numbers. This post will try to keep the Windows 10 version Numbers and Windows 10 build numbers. The latest version of Windows 10 was released on November 14th, 2023 (KB5032189).
There were many issues with Windows 10 upgrades and the quality of upgrades. There are fewer hotfixes released in the latest versions of Windows 10. So Windows 10 quality is getting stabilized with new versions.
The next generation of Windows might be announced at any time. I have a more detailed blog post in this Microsoft Almost Announced The Next Generation Of Windows | Windows 10X Is Not The Next Generation Anymore. You can check Windows 11 build numbers are also documented.
You can download the Windows 11 Onboarding Kit to help you prepare, educate, and support people in your organization before, during, and after Windows 11 migration. I know many organizations have already started the preparation work for Windows 11 migration.

Windows 10 Version Numbers Vs. Windows 10 Build Numbers
Windows 10 version number is in the year and half of the year (H1 or H2). For example, the Windows 10 version released in April (4th Month) 2020 is Windows 10 20H1.
- The first two (2) digits of the Windows 10 version are taken from the release year. In the above example (Windows 10 21H2), that is 2021.
- The last two (2) digits of the Windows 10 version are taken either from
- the first half of the calendar year – H1
- or the second part of the calendar year – H2.
- In the above example – Windows 10 was released in the second half of the year.
- Special version numbers for the major.minor.build.rev of Windows 10 structure are as follows – Windows 10 – 10.0.19044.1202
- Major = 10
- Minor = 0
- Build = 19044
- Rev = 1202
Windows 10 build number is based internal development cycle. I think it’s based on the code base of the Windows operating system. Windows Server 2022 build number is 10.0.20348.169.

Windows 10 Wrong Version Numbers
Major versions of Windows 10 for 2021 would be 21H1 and 21H2. There are some confusing scenarios with Windows 10 21H1 OS Versions. You get the wrong version number, like 10.0.19041.928, when you try to check the version number from the SCCM Console Operating Systems Node.
How to Find the Latest Windows 10 Version Number?
Let’s find out how to Find the Latest Windows 10 Version Number using the built-in Windows utility (WinVer.exe) and registry editor. You can click on the Start button and type WinVer to launch WinVer.exe.
The next option is to double-confirm the version number from the registry editor. You can launch the registry editor you using the following method. You can click on the Start button and start typing regedit to launch the Registry Editor utility.
You need to navigate it to the following path in the registry to get the details of the Windows 10 20H1 version number/build number. Check the CurrentBuildNumber string value to find out Windows version details.
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\CurrentBuildNumber
Windows 10 21H1 Version Number | Build Number Structure
Let’s break down the Windows 10 21H1 and Windows 10 21H2 major.minor.build.rev version number structure for all of you. When you try to find out the version number using the winver command or from the registry, you get only the last two parts of the version numbers of Windows 10.
Windows 10 21H1 Version Number 10.0.19043.985
Windows 10 21H2 Version Number 10.0.19044.1319
So the question is how to get the full version number of Windows 10 21H1 and 21H2. I think it’s easy to get the version number if you understand the structure of the version numbers. There are 4 (four) parts to the version number structure.
The first 2 (two) parts of version numbers are common for all the Windows releases until now. The Windows 8, Windows 7, and Windows XP versions of Windows releases. It is the same for Windows 11 and Windows Server 2022.
- Windows 10 Major Number = 10
- Windows 10 Minor Number = 0
- Windows 10 Build Number = 19043
- Windows 10 Rev Number = 985

Dope. Update though with 1909
Done
Very convenient post for managing my Azure AD version policies.
Could you update with 20H1 and 20H2?
Nevermind I just saw that they’re already there.
Only missing in the images.
Thank you for the feedback. I will try to update the image as well.
Many Thanks for this. Really useful. Do you keep this updated?
I’ll try to with major release of Windows 10
Do you think anything is missing
HAVE WIN 10 64 PRO 20d2???
not listed??
20H2 is already there in the list I suppose
Hi,
I’m trying to use System Center logs to automatically detect the update status of the computers that we have, these logs justs contains versions in the following format (10.0.18363, 10.0.17134…) and I would like to be able to mantain a CSV with each new version and build to match it. Where did you get this information from?
Thanks
“WINVER” the utility gives you the .18363 but all Windows 10 will have the 10.0 version as the prefix to .18363.
My Win10/64 give wrong version # with the RtlGetVersion API. It report Build # 7600.
I can not find, why it has been changed and how can I reset to the actual 21H1 vesrsion ?
Thanks in advance if you have any idea.
Endre
May I have question about wrong build number report ?
Endre
Hi Anoop,
Thanks for your detailed version update history. much appreciated!
1. I have a PC that only has the base version of Windows 10 version 1507 build 10240. whats the easy way to bring it to latest 21H2 build. I tried to download few KB up from 21H1 to 2004, but the update couldn’t complete as its not suitable for build 10240 version.
2. can you specify the best reliable source to download the respective KBs? some build version doesn’t get the KB numbers in the chart.
1. I think the best way in the scenario is In-place upgrade https://www.anoopcnair.com/windows-10-21h1-upgrade-using-sccm-task-sequence/
2. The best way is to use SCCM or Intune to patch Windows devices regularly. Otherwise manual method to download KBS https://www.catalog.update.microsoft.com/search.aspx?
Do you know why the major version has not been changed to 11 for W11?
No, why should it be changed? Because Windows 11 and all other versions are all built on the same base OS … Microsoft is just adding new additional code on top of the previous versions. Hence the major version is not changed.
I don’t think it will ever change until they reach some other limitation. Or Microsoft needs to build a new OS ground up to change the major version.
I don’t accept a new Windows ground-up build version anymore.
Need 22h1 and 22h2
There is no 22H1. Microsoft stopped the release of updates every 6 months. Now onwards yearly you will have only one version of Windows 10 and Windows 11 released. That will be Windows 10 22H2 and Windows 11 22H2. So there won’t be any Windows 10 22H1 and Windows 11 22H1.
Can’t find any info on 22H2 , 19045.1766.
Only 22H2 stuff.
Cannot download or load windows 10.0.19041 1 what is command number
Hi Anoop,
My Desktop version reported by Winver is – 21H2 (OS Build 19044.1889) and Build version reported by Regedit is – 19044. All update on my Desktop are failing with “Some update files are missing or have problems. We’ll try to download the update again later. Error code: (0x8007000d)”. I have tried all solutions reported on various websites but without any success. How can I apply the latest 22H2 upgrade and keep the PC in regular patch cycle. Will the method reported by you will work?
1. I think the best way in the scenario is In-place upgrade https://www.anoopcnair.com/windows-10-21h1-upgrade-using-sccm-task-sequence/
2. The best way is to use SCCM or Intune to patch Windows devices regularly. Otherwise manual method to download KBS https://www.catalog.update.microsoft.com/search.aspx?

Hi Anoop,
19044.2846 is 11th April 2023 release but added her as 9th May 2023
Fixed the issue now. Thank you.
Seems odd you need to add a custom MOF to add the Rev. number to Hardware Inventory. Can’t find anyone that explains the best way to do this.
