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.
