Various Microsoft documents refer to Windows build numbers. There was no build 19024 released publicly, but there was a build 19025, suggesting that build 19024 was a build kept internal at Microsoft and never released. For example, build 19023 was an early version of 20H1 released to Insiders during the development process. The numbers in between are development versions of Windows 10 that are sometimes released in preview form to Windows Insiders. This is true-both 20H2 and 19H2 were minor updates with few changes over the previous release.

These numbers tell us something interesting: 20H2 looks like a minor update to 20H1, and 19H2 looks like a minor update to 19H1. Only the last five digits change.Īlso, there are minor build numbers-the stable version of 20H2 is initially "19042.572", but the "572" number will increase as Microsoft issues minor patches for the update.

The October 2020 Update has the OS build number "19042." Technically, the full build number is "2," to indicate that it's a Windows 10 build. When the stable update is released, it still has this OS build number. During the Windows development process, each "build" of Windows 10 released to Windows Insiders has its own build number.Īfter much testing and bug-fixing, Microsoft settles on a final build that will be the stable version of the update. Windows 10 also has operating system (OS) build numbers. (Microsoft gave it this version number retroactively, as it was released that month.)

Here's a list of version numbers for Windows 10 updates: Microsoft is confusing once again here, and the version number seems to refer to the month the update was "finalized" (and perhaps released to Insiders,) while the marketing name refers to the update the month was released. September 2020.īut this is the October 2020 Update, right? Well, yes. The first two digits represent the year and the last two digits represent the month.

The Windows 10 October 2020 Update is technically Windows 10 version 2009.
