Hi,
In this case, you can modify or reset the IE setting on the Host and use command line to affect the Clients with new group policy
Close all open windows and programs on Host PC
Open Internet Explorer, select Tools > Internet options.
Select the Advanced tab.
In the Reset Internet Explorer Settings dialog box, select Reset. Or you can do some modifications
When Internet Explorer finishes applying default settings, select Close, and then select OK. Restart your PC to apply changes
Then use command line: gpupdate /force
That will apply your changed GPO settings right away. Or you can just wait a couple of hours because GPO is refreshed every 3 hours in random intervals.
