          >>> help abou* 

          >>> help *user* 

you can also use Get command

         >>>  Get-Command *user* -module ActiveDirectory


Some commands are not installed in your system and will not be found on the system 

find command -- reaches out to power shell galary

>>> Get-Module -- tells me which modules are loaded in my sesssion it doesnt tell you what modules you have installed in your computer

 >>> Get-Module --ListAvailable 

>>> Find-Module Az

>>> Find-Module Az -AllVersions

It lists all available versions of the Az PowerShell module that are published in the PowerShell Gallery (online repository), not just the latest one

>>> Install-Module Az
