G'day, I'm a computer dope and I'm stuck on this. I'll try and explain what's happened and I apologise for being long winded.

I have a load of photos in files on our windows 11. I can see them in the file in thumbnail but when I click on them to open them up (make bigger, full screen) I get a pop up on the screen saying "You'll need a new app to open this ms-paint link". Next line says " Look for an app in the Microsoft Store" There's a tick box that says Always use this app and an OK box but nothing seems to work when ticking and Oking?

My wife Bev has a water ski friend who is a computer wiz but sadly I have a few to many naughty photos on this computer to be risking having anyone looking through it.

Any help at all would be greatly appreciated. Thank you, Steven.
