Finding system information on Windows

In practical system administration, it is sometimes necessary to record edition and/or version of Windows along with the product key (for example, before installing a non-Windows OS with the view of using the Windows product key on a different machine). This can be accomplished by using systeminfo and piping its output to findstr:

systeminfo | findstr /B /C:"OS Name" /C:"OS Version"

This will output the requested data fields in a format similar to this:

OS Name:                   Microsoft Windows 10 Home
OS Version:                10.0.14393 N/A Build 14393

To display Windows 8.1 or Windows 10 product key, use wmic:

wmic path softwarelicensingservice get OA3xOriginalProductKey

Needless to say, all of the above has to be done while running the command line interpreter with administrative privileges.
