This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
I have upgraded the Windows version from 1909 to version 21H1. After the restart, I found out that Active Directory was missing. How will I get it back?
I am new to AD so asking how to install it.

Hi @Sule Oebao
From the Start menu, select Settings > Apps.
Click the hyperlink on the right side labeled Manage Optional Features and then click the button to Add feature.
Select RSAT: Active Directory Domain Services and Lightweight Directory Tools.
Click Install.
When the installation completes, you will have a new menu item in the start menu called Windows Administrative Tools.
