Yesterday I answered on this question in delphi programming mailing list. I want to post this answer as tip because I sure that this question can ask a lot of developers but to find an answer is not easy task.

So if you need refresh a desktop in run-time, you can execute a next procedure:

SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, NULL, NULL);

This code will refresh a desktop image and re-read the icons for files with registered extentions.

PS: you can do a same if you press a right mouse button on desktop and select Update item.
