    I've built my own application that searches for files and have set it to run as
    administrator, however it won't read/detect most of the sys files in
    c:\windows\system32\drivers. I did some checking and most cygwin EXEs
    also have the same problem.

    For example, if I cd to that directory and do a "dir" I see all the files (334 files).
    However, if I do an "ls" (cygwin ls.exe) it only lists 10 files. So I think it's the
    same problem.

    I have turned off all the file hiding options in explorer and the files show up there.
    I don't want to modify these files or their permissions, just list them and read them.

    When I look at the effective permissions tab for these sys files, it says that
    Administrator DOES have read and list permission, though they are owned
    by TrustedInstaller.

    Is this WFP (windows file protection)? When I researched WFP it said it only
    protected against modifications to files, not reading them.

    It seems like Windows 7 is letting only microsoft EXEs read these files, but all other
    EXEs, even if being run by administrator, are denied. (Another example, cygwin

    Anyone know what's going on here?

    I have the same problem. It must be a Cygwin bug.
