Hello Muthupandi Muthurathinam,
Thank you for posting in Microsoft Community forum.
Does the problem occur before the machines joined to domain?
Or does the problem occur after the local user account sign in the machines?
You can try to check if there are any GPO settings that make the apps gets installed automatically.
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".
For checking User Configurations within gpresult, we can follow steps below.
Logon the machine using normal domain user account (that applies this gpo).
Create a folder named F1 in C drive.
Open CMD (do not run as Administrator).
Type gpresult /h C:\F1\gpo.html and click Enter.
Open gpo.html and check if there are these gpo settings under "User Details".
I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Best Regards,
Daisy Zhou
