Thanks, pjfarr. I've now tried that alternative Powershell procedure.
Get-AppxPackage –AllUsers returns a list that includes the Photo app, but when I use the full name to remove it, the app is not found.
If I use Get-AppxPackage without the qualifier (which I guess lists the packages for the current user) Photo isn't listed. Yet if I click on a .gif, it opens in Photo
I'll need leave it for now as I've other things to do - for the present, I'll manage without using the file associations, use right-click OpenWith, or open the App I want to use and browse to the file. Thanks for your help - I'll post here if I find out any more.
