Your network contains an Active Directory domain. All client computers run Windows 8.1 Enterprise and are
located in an organizational unit (OU) named WindowsSComputers.
The network has Windows Server Update Services (WSUS) installed. All of the computers are configured to
receive updates from WSUS.
The network administrator creates a new computer group named Win8Computers in WSUS.
You need to ensure that the Windows 8.1 computers receive all of the updates that are assigned to the
WinSComputers computer group.

Explanation:

the computers by using Group Policy or registry keys.
