Running PowerShell command Get-ADUser from Windows 10

Question

I am Trying to run the PowerShell command Get-ADUser on my Windows 10 Pro Laptop.
I am getting below error.

Get-ADUser: The term 'Get-ADUser' is not recognized as the name of a cmdlet.....

After googling I got to know I need to run command Install-Module ActiveDirectory, but this command given error that ActiveDirectory module not found.

I did try to install all the RSAT Tools but I see it is in Staged state and not sure how to move them to Installed. I did google this issue and not able to fix it.

PS C:\WINDOWS\system32> Get-WindowsCapability -Online -Name "rsat*" | Select-Object -Property DisplayName, State

DisplayName                                                                         State

Also from the Settings > Apps > Optional features > Add feature I am getting error when I try to install RSAT: Active Directory Domain Services and Lightweight Directory Services Tools.

As per some of the seggetions I need to run the PowerShell command Stop-Service -Name wuauserv then install again, but it did fail in my case.

Issue that I am facing:

1. I want to run Get-ADUser command from Windows 10 but I am not able to.
2. I did not find a step-by-step guide which can describe how to use powershell command with ActiveDirectory on Windows 10 Pro.
3. I am not sure if I need to have the AD Domain Controller, if I need how to configure.
4. I have all the "Windows Administrative Tools" installed on my Windows 10 Laptop but not sure how to configure these tools to my Azure AD and if these tools are required for running Get-ADUser command.

Details:
Windows: Windows 10 Pro 21H1
PowerShell: version 5.1.19041

--------------------- Update --------------------------

I got the all the RSAT modules/services installed on my Windows 10 Laptop. The issue was related to the recent update to my Windows.

I have to enable below policy on my Laptop:

Edit Group Policy > Administrative Templates > System > Specify settings for optional component installation....

1. Select CheckBox: Enabled 
2. Select CheckBox: Download repair content and optional features directly....
