chm display small box with "x" instead of graphic content

ALL my chm files display an "x" in place of graphic content. Those same files display properly on all my other Win 10 Pro machines. I'm currently at 1909 and it seems the problem started as long ago as 1809......... maybe even 1803.

Any suggestions?

 

Display of names of folder contents

Not sure if this is a Win10 problem or a software problem but here goes: When I open a folder the contents are always displayed as icons, which forces me to change it to a list each and every time, which is a time-consuming nuisance! Is there any way to
show the contents as a list by default?

Many thanks for any help.

 

RetailDemo Offline Content?


Was cleaning up my 10162 install using cleanmgr. One option on the list was "RetailDemo Offline Content", it was 100MB. Not sure what this is, before I delete it. Suggestions?
