Hi everyone, this is my first post.

I did some searching earlier and I saw posts relating to Windows Explorer icons https://irfanview-forum.de/showthread.php?t=7275.

However this relates to Universal Windows App icons, I have attached some images to show.

In this image, Alarms & Clock appears fine

However in this image, it's icon is replaced by Irfanview

And the same happens to Mail and Settings

I have no idea how to fix it. I removed all irfanview file associations and then custom set them myself, and I cleared the Windows icon cache. Please help because this is really annoying.
