I was a Windows 10 insider previewer and, since some build ago, it is not displayed any more, on the right down side of the desktop, the build number.

How can I see now the version number and understand if I have been already updated to the final release? This is also important if you are a developer because particularly interested because the final release of Visual Studio 2015 needs to be installed after the final release of Windows 10 if you are going to develop Universal Apps.

I asked to the MSDN support and I received a quick answer to my questions 😉

First of all to see the running build it is sufficient to right click on the menu icon and choose “run” (or Windows + R keys), type msinfo32.exe (press enter): the following windows will open where you can see the “Version” and the “Hardware Abstraction Layer” (e.g. 10.0.102040.16392). You can see the version also from a command prompt where at the top it should be found “Microsoft Windows [Version 10.0.10240]

The final windows 10 build is 10240 version: the Hardware Abstraction Layer – version represents the HAL to certain kinds of hardware (it can be, for example,  10.0.102040.16392 or 10.0.10240.16405): therefore both windows preview build 10240 and the final windows 10240 build are the same. The numbers vary depending on the type of hardware you have: some people will have windows version 10.0.10240.16392, version 10.0.10240.16393, version 10.0.10240.16397 and others version 10.0.10240.16405.

Note, if you are a developer, that after having installed Visual Studio 2015, including the optional component to develop Universal Apps, you’ll fine in C:\Program Files (x86)\Windows Kits\10\Platforms\UAP a directory 10.0.1.10240.0 that is related to the SDK for that specific version.
