Hello Nasir Uddin3,
Thank you for posting in Microsoft Community forum.
I find the two policy settings you mentioned are under User Configurations.
1.What did you define in "allow Windows to run Specified Programs only"?
2.What did you define in "show only specified items in the control panel policy"?
3.If you only set policy "show only specified items in the control panel policy" and remove "allows Windows to run the Specified Programs only policy", does it work?
If you have any question or concern, please feel free to let us know.
Best Regards,
Daisy Zhou
