People... Stop randomly deleting these files or worrying about them. Desktop.ini files (as the ini hints to for those familiar) are configuration files used by windows to do per folder configurations.
If you do delete these there also is no reason to worry, as that will just reset your folder configuration, for that particular folder, back to default. If you want custom folder configurations, then keep them, if you don't then delete them. If you don't want
to see them then disable the viewing of hidden files and folders... if you want to have hidden files visible then you can use this command to mark the file as a system file, so it will only show if you also choose to make system files visible:
attrib +s +h <path\directory name> /s /d
