How to Remove a Windows 10 PC from a Local Active Directory Domain

information   Information
A network based on a Domain provides centralized administration of the entire network from a single computer which is called a server. A Domain provides single user login from any computer connected to that network within the network perimeter. Users are allowed (or restricted) to access resources depending upon the permissions they have.

If your Windows 10 PC is joined to a domain, you can remove the PC from the domain if needed.

This tutorial will show you how to remove a Windows 10 Pro, Enterprise, or Education PC from a local Active Directory Domain in Windows 10.

You must be signed in to an administrator account on your Windows 10 PC to leave a domain.
