Can lead to disappearing of special behaviour in personal folders
If I apply a new icon package through IconPackager which includes custom icons for the personal folders like "desktop" and "music", these folders' desktop.ini files lose the system attribute.
This makes them visible even if protected operating system files are set to hidden, and deletable. Deleting one of these files can lead to the loss of special behaviour of these folders, which cannot easily be restored.
If IconPackager edits or (re)creates a desktop.ini, it should get the read-only, system, and hidden attributes set always.
Behaviour seen on Vista 32-bit.
Fix: Open cmd.exe with administrator priviliges on the system drive root (C:\).
Type attrib /s +r +s +h desktop.ini and let it run, ignore any errors.
