Domain Computer can be added into WSUS console by using Group Policy. But how about workgroup computer !
You can add workgroup computer into WSUS console by using registry.
I have created two script to simplify your tasks.
1. File: wsus.bat
@echo off
::
Pause
net stop "wuauserv"
Echo importing wsus.reg
%windir%\regedit.exe /s c:\wsus.reg
echo wsus.reg imported successfully
net start "wuauserv"
echo forcing update detection
wuauclt /detectnow
pause
Note: Stop the Windows Update Service, execute wsus.reg and start Windows Update Service. Perform manual detection by using the command wuauclt /detectnow
2. File:wsus.reg
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate]
"WUServer"="http://wsussvr01"
"WUStatusServer"="http://wsussvr01"
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU]
"NoAutoUpdate"=dword:00000000
"AUOptions"=dword:00000004
"ScheduledInstallDay"=dword:00000000
"ScheduledInstallTime"=dword:0000000d
"UseWUServer"=dword:00000001
"NoAutoRebootWithLoggedOnUsers"=dword:00000001
Note:-
a) WUServer and WUStatusServer - specify your WSUS server using the following format http://wsus server name
b) Value: NoAutoUpdate
•0 - Enable Automatic Updates (Default)

g) NoAutoRebootWithLoggedOnUsers -NoAutoRebootWithLoggedOnUsers is enabled which Specifies that to complete a scheduled installation, Automatic Updates will wait for the computer to be restarted by any user who is logged on, instead of causing the computer to restart automatically in 5 minutes to complete the installation.
Note: Copy both files into C:\ drive and run wsus.bat
