How do you find details about your computer operating system using Windows Management Instrumentation?

Call up WMIC from a command prompt to begin as shown.e  It is better to start the CMD  as an adminsitrator.
-----------
C:\WINDOWS\system32>Wmic
wmic:root\cli>
----------------
Now you are at the root, use the following statement to find the help file for the Operating System (OS):
------------
wmic:root\cli>OS /?
OS - Installed Operating System/s management.
HINT: BNF for Alias usage.
( [WMIObject] | [] | [] ) [].
USAGE:
OS ASSOC []
OS CALL []
OS CREATE
OS DELETE
OS GET [] []
OS LIST [] []
OS SET []
-------------------
You should get help for each of these as well. Here is an example for OS Get:
Execute the following statement:
-------------
wmic:root\cli>OS GET /?
Property get operations.
USAGE:
GET [] []

Now here are a few things about my operating system (Windows 10 Professional)

This was just a sample of what you can find. You can try a whole lot on yourself.

Do you know these Power-Shell commands for Network Connectivity?

These are some of the commands that you may need to note. Although similar information is obtained by the Windows commands as well.
