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.  This information isn’t typically 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:
