Default app windows 10 64 21H2?

Question

Software and Internet Services

Hello, dear experts, I am addressing this question, reinstalled Windows, installed 21H2. that is, the last release, and now she began to infuriate me, I'm trying to put Xnview as a picture viewer. but it wasn’t there, at first this program was not in the default program selection field, I found on the Internet how to make it appear in the list of programs, set it by default, everything seems to be beautiful, I try to open any graphic file, Windows shows big and thick and opens it with my promotor, I go to the default applications, Xnview is there. I open applications by files, there is also Xnview opposite the graphic files. and even in the settings of the program itself, in the options they try to match the files, it refers to the default program, well, it’s already there, here’s how to deal with this .... why fight, don’t talk about Linux,
who has any suggestions on this matter, maybe you can fix it in group policies or register it in the registry, I will be grateful
