Hi
After the workstation updates the system, it needs to be added to the domain first, and then the workstation is placed in an OU on the domain controller side, so that the workstation can accept the relevant group policy settings of the corresponding OU.
For how to add a domain to a workstation, you can refer to this document:

For how to add computers to OU, you can refer to this document:
