In this post, I will try to keep the Windows 10 version Numbers and Windows 10 build numbers. There were many issues about Windows 10 upgrades and the quality of upgrades. There is less number of hotfixes released in the latest versions of Windows 10. So Windows 10 quality is getting stabilized with new versions.

TL;DR
Windows 10 Version Numbers Vs. Windows 10 Build Numbers
Windows 10 version number is in year and month format. For example, Windows 10 version released in the year April (4rd Month) 2020 is called Windows 10 2004.
- The first two (2) digits of the Windows 10 version is taken from the year of the release. In the above example (Windows 10 1903), that is 2019?
- The last two (2) digits of the Windows 10 version is taken from the month of the release. In the above example (Windows 10 1903), that is march 3rd month of the year.
- Special version numbers for major.minor.build.rev of Windows 10 structure is as follows – Windows 10 2004 👉 10.0.19041.329
- Major = 10
- Minor = 0
- Build = 19041
- Rev = 329
Windows 10 build number is based internal development cycle. I think, it’s based on the code base of Windows operating system.
- The first Windows 10 build number is 10240
- The last Windows 8.1 build number is 9600
- The last Windows XP build number is 3790

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
