A few weeks ago, I noticed that the typical icon for my PaintShop Pro 9 changed, both in the taskbar and in the Start,It was replaced by a "generic" icon. I thought it was due to PSP9 being so old it might have been affected by something in Windows 10 updates.

Recently, I also noticed that the same thing happened to Adobe Acrobat. So far, those are the only two programs where the icons have changed.

I have no idea what happened or how to solve that. Any suggestion?
