I removed a program called Aston Shell from my system but afterwards most icons that belong to registered file types (such as Word document, BMP-files) have lost or aren't shown. Instead the icon picture is the one assiocated with unregistered file types. However, Windows recognizes the file types it should (open correct programs) but the icon picture is wrong. How can I fix this? I read some tips about deleting 'shelliconcache'-file but there isn't one in my Windows folder. I have XP with SP1.
