"Open all PDFs in Acrobat Reader"

[MajorKay]

Hello,

I've recently started installing Adobe Acrobat (Reader) during OS installaiton via Confoguration Managet from the Microsoft Store using Winget - the installation works perfectly fine, after the installation finishes I can login to the system and I can ope PDFs via the Reader application. When I open a PDF I get a popup message (screenshot below), which suggests that the reader application is not set as the default app to open PDFs and it is in my case, as I have a GPO that set's "Adobe Acrobat" as the default app to open .pdf files (screnshot below).
Is there a GPO or registry entry that can hide the message for all users in a corporate environment?

P.S.

Can Adobe make up their mind on how the products are named, be consistent in the naming and not rename them so frequently? 
In Control Panel I can see "Adobe Acrobat", then I open the applicaiton tand he title bar shows "Adobe Acrobat Reader" and the file association shows "Adobe Acrobat" - this is very confusing for an IT person.

Hey Abambo,

thanks for the link!

If I understand this correctly, the solution in the link offers a registry export from a properly configured device, so that later on it get imported into a new device - this would work one time, right?

I'm looking for a solution that utilizes a GPO that sets file to application associations (the GPO will overwrite the associations each time the GPO kicks in).

Unless, I misounderstood your intentions and you meant to hide the prompt using registry?

You talked about GPO and registry entry. I'm knowledgable enough to understand the term "GPO", but my time in system management was during the mini-computers and maiframes period. I never managed countless Windows workstations. At that point I moved on and worked as a Graphics Artist and as advisor. <humor> I always had the good ideas and the others were sweating to implement that, because bosses loved my ideas…</humor>  So this time you need to check, if my link is useful for you. I can't judge that from a distance.

Thanks Abambo,

in my case a registry setting won't help as the file association will get overwritten every time the computer processes GPO.
