I missed this crucial fact so far. Now I was able to reproduce it. It appears that the "shared" tag has nothing to do with sharing in a network sharing sense. The "shared" tag attached to files and directories in your Vista home folder indicates that this file or folder has permissions which allow a "normal" local user other than yourself to access this file or directory. Experimenting with various permission settings, I found that the "shared" tag only shows up if the file/dir has any combination of ACEs for the Users group or for Everyone, regardless of the actual permissions granted in the ACE. Apparently this is some sort of "security" consideration new in Vista. Given that, there's nothing Cygwin can do about it. POSIX permissions require to have settings for Everyone and, depending on the /etc/passwd settings, the Users group. I'm certainly not going to cripple Cygwin's POSIX permission facility just so that Vista doesn't show this weird "shared" tag. There are a couple of ways to go ahead, in the order from good to bad: - Find out if there's a way to switch off this crappy Vista feature and switch it off. - Move your Cygwin home directory outside of the C:/Users tree. There's no reason to keep the Cygwin home directory in this tree. I'm using C:/cygwin/home/corinna and/or C:/home/corinna for years and I haven't had any problems due to that. - Set CYGWIN=nontsec and lose POSIX permissions.
