XP Icon Caching Mania ...

I've just experienced a couple of hours of total frustration fighting with
XP's icon caching. I wanted to add a document icon file association for my
application ... added it to my app, built it (icon in correct place
following main icon) ... installed it and registry association confirmed as
correct ... and file association icon displayed correctly. Decided to
improve the quality of the document icon ... built, installed ... and no
change in displayed icon ! At first, I thought that the icon hadn't been
updated in my app.

I tried rebooting ... deleting IconCache.db ... to no avail. Altering the
registry to point at the icon directly did work but restoring it back to the
application returned the old icon again, I also found that changing the
association to point at the app's main icon also worked.

In the end, I used Tweakui to do an icon rebuild and apart from messing up
all of my desktop icons positions it did correct the problem.

Can anyone explain where and how XP manages to cache and associate old icons
that no longer exist ? ... I don't really want to keep using Tweakui's
repair function.


Thanks,

Andrew
