Icon problem

Hi, I have a recurring Icon problem and would like to get some help from the knowledgeable crowd here at Tenforums

My problem mainly manifests itself as an inability to show certain Icons.
Like the Windows Mail icon on my desktop for instance. Once in a while it becomes blank.
I then use sfc/scannow & ran the Rebuild_Icon_Cache.bat, which fixes my problem... for a while.
After a couple of weeks or so I end up with the same problem, usually the Windows Mail icon...
But other desktop icons are sometimes affected with the same problem. Not all tho! Just a few.

I find it the most annoying when I use Chrome or Edge...
There the problem occurs with tiny icons, like an arrow on a tile to click on, or other objects.
Example, I use a site called Doccle to archive documents, with 4 user actions (save, delete etc) In the following screenshot you'll see 4 icons, of which one (little square on the right hand side) is wrongly displayed, or not displayed at all.



Another example, although I have no screenshot of that, is when I do online banking I have to use a card reader to verify my transaction. On my screen I see a window appear with instructions, like Login, Sign, Buy etc yet the icon that contains this text is also displayed as in the screenshot above, just a small square. This makes it difficult to discern which is which!

I'm not entirely sure if the Rebuild_Icon_Cache.bat tool fixes my issues, because each time I ran it I see "IconCache.db files have been successfully deleted" yet as you can see in the following screenshot I have certain entries with "Access denied".



Maybe there lies my culprit, I don't know, thats why I come here because I'm sure some of you know!

Thanks in advance Carlo

As another example of my problems I'll upload another screenshot of something I see regularly, namely no picture where there ought to be one!



Can somebody help me out?
