Windows Version Numbers
Windows Version Numbers Information
This post serves as a quick reference of Windows Version numbers for both server and client Microsoft Operating Systems.
Windows 10 and Windows Server are broken down in the first sections in greater detail as they are moving into a Windows as a service model.
A complete list of all operating systems versions is listed in the Operating System Version Summary section towards the end of the article. I have included a few lines of PowerShell code at the bottom to quickly identify the exact version of Windows that you are running.

Checking your Windows Version with PowerShell
In modern Operating Systems there are a lot of components that make up a full windows version number:
10.0.1607.14393.1794
This version number identifies the major, minor, version, build, and revision components of the server or client you are running. Full version information isn’t readily available in any of the GUI menus and it’s easiest to pull it from the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion
I provide a detailed breakdown of the components that makeup a windows version number in the following post: Windows Release Channels Explained
Here is a quick PowerShell example of how to pull all the needed components to determine the full Windows Version Number that your device is running:
