How workgroups work on windows

A windows 10 pro workgroup is a logical grouping of networked computers that share resources, such a files and printers. A workgroup is also called a peer-to-peer network because all computers in the workgroup can share resources as equals(peers) without requiring a dedicated server.

Each computer in the workgroup maintains a local security database, which is a list of user accounts and resource security information for the computer on which it resides. Using a local security database on each workstation decentralizes the administration of user accounts and resource security in a workgroup.
A workgroup can contain computers running a server operating system, such as windows server 2016,as long as the server is not configured as a domain controller, in a workgroup, a computer running windows server n2016 is called a stand-alone server.
Because workgroups have decentralized administration and security, the following are rue:

• A user must have a user account on a local computer if that user wants to log on to that computer locally
• Any changes to user accounts, such as changing a user's password or adding a new user account, must be made on each computer in the workgroup. If you forget to add a new user account to one of the computers in your workgroup, the new user cannot log on that computer and cannot access resources on it.

Workgroups provide the following advantages:

•  Workgroups do not require a domain controller to hold centralized security information, making workgroups much simpler to configure and manage.
• Workgroups are simple to design and implement. Workgroups do not require the extensive planning and administration that a domain requires.
• Workgroups provide a convenient networking environment for a limited number of computers in close proximity. However, a workgroup becomes impractical in environments with more than 10 computers
