Fatal Error: A required configuration value was
not found in the system. This is usually caused by installing WSUS through
PowerShell and not specifying a configuration file. Review the article Managing

The problem is that when you activeated the post install phase, this file was not properly updated by the WSUS installer.
<?xml version="1.0" encoding="utf-16"?><INSTANCE CLASSNAME="ServerComponent_UpdateServices_Services">
<PROPERTY NAME="ContentDirectory" TYPE="string"><VALUE>D:\WSUS</VALUE></PROPERTY>
<PROPERTY NAME="ContentLocal" TYPE="boolean"><VALUE>true</VALUE>
</PROPERTY></INSTANCE>
Once we fix it we run the post install again but we see a different error
Still it didn’t have an instance, oops..

We can see that from the log it can't find the instance for WSUS. In this example we are using SQL express and not the Internal Database so back we go to addd the instance in.
C:\Windows\System32\ServerManager\ComponentConfiguration
Open the updateServices-DB.xml
<?xml version="1.0" encoding="utf-16"?><INSTANCE CLASSNAME="ServerComponent_UpdateServices_Database"><PROPERTY NAME="InstanceName" TYPE="string"></PROPERTY></INSTANCE>
Add the instance to the file. Here we will use the default instance for SCCM, ConfigMrgSec
<?xml version="1.0" encoding="utf-16"?><INSTANCE CLASSNAME="ServerComponent_UpdateServices_Database"><PROPERTY NAME="InstanceName" TYPE="string"><VALUE>ServerName\CONFIGMGRSEC</VALUE>
</PROPERTY></INSTANCE>
FINALLY IT IS ALL DONE!
This will stay in the file for future use.
You can also try to do the command manually from the command prompt. The only problem is that the .XML files aren't updated.
C:\Program Files\Update Services\Tools
wsusutil.exe postinstall SQL_INSTANCE_NAME="SERVERName\ConfigMgrSec" CONTENT_DIR=D:\WSUS
