It reacts just fine, as there is no internal dependency on having the overlay handler *actively* installed as an overly handler. There is no hidden magic here. The COM object is still registered, BTW. It's just no longer called by explorer, because explorer enumerates HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers and calls all COM objects there, querying them for the COM interface IShellIconOverlayIdentifier and calling GetOverlayInfo() (http://msdn2.microsoft.com/en-us/library/bb761265%28VS.85%29.aspx) If an overlay handler is not registered at that registry location, it's *simply* not called. That's all. Not the slightest magic going on here. I can furthermore report that I have just successfully uninstalled TortoiseHG 0.4rc1 *after* having first "hacked" the registry as I wrote in my OP. The uninstaller reported "TortoiseHg was successfully removed from your computer" and I found nothing fishy after that. Reinstalling TortoiseHG 0.4rc1 after that worked fine as well -- the overlay icons and the registry keys were again there, as before my registry "hacking". --Adrian ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
