"Full computer name" and the "Workgroup". For a typical network environment, we

the PC computer name or the PC workgroup, click the "Change..." button.
After clicking the "Change..." button, the change window appears. Input the new
computer name and/or the new workgroup in the respective fields and then click "OK".
When applying the new computer name and the new workgroup, the system will

restart and let the PC reboot.
