            Hi all,

    Let's have a look at Windows 2000/XP ACL inheritance oddities :
    1/ Create a new file named "test.txt"
    2/ Break ACL inheritance and apply custom ACL
    3/ Rename "test.txt" to "othertest.txt"
    4/ Check that ACL has not changed

    Now :
    1/ Use REGEDIT and create a new key (in HKCU for example) named "key"
    2/ Break ACL inheritance and apply custom ACL
    3/ Rename "key" to "newkey"
    4/ ACL has been reseted and is now inherited from parent !

    It looks like the "rename" paradigm does not make sense for registry
    keys and REGEDIT has to create a new key, copy values, and delete the
    old key.

    Bug or feature ?
