Hello
Thank you for your question and reaching out. I can understand you are having issues related to GPO missing.
- As you have mentioned that downloaded this, extracted all files and placed them in the Policy Definitions folder in SYSVOL. Can you please verify if you have configured the settings from Group Policy Management console after copying new ADMX files.
- Please also verify that AD replication \ SYSVOL replication is good in health and all are synced.
- On the Client computer run gpresult /h C:\temp\gpresul.html to verify that GPO have been successfully applied.
