Hello Jimmy Afflick,
Thank you for posting in Q&A forum.
1.Does the problem occur on all the domain machines in this one particular environment? Or only one or some domain machines?
2.Do all the three browsers still auto update on the domain machines in this one particular environment? Or only one or two browsers still auto update?
Please check the group policy apply result on one problematic machine, for checking Computer Configuration within gpresult, we can follow steps below.
Logon this machine using administrator account.
Open CMD (run as Administrator).
Type gpresult /h C:\gpo.html and click Enter.
Open gpo.html and check gpo setting under "Computer Details".
If you can see all the gpresult information on this problematic machine, you can check if the registry data you mentioned is changed manually on this machine.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best Regards,
Daisy Zhou
