Ownership of Registry Keys?

    Ownership of Registry Keys?


    I have come across an issues with potential problems with ownership of registry keys on my machine.

    Up until now, I was not aware that registry keys had owners, like directories. Why is this?
    Is there any link between the ownership of directories and registry keys.

    I haven't deliberately changed ownership of Registry keys, is there any way they can have been inadvertently changed through some other Windows function or Program.

    I wonder if anyone can tell me more about this, and if there is anyway to simply reset ownership for the standard Windows keys.

    You can reset permissions using secedit or Microsoft fixit 50198 - see here Reset Windows Security settings to default values in Windows 8 | 7

    Like other permissions the idea is to stop programs and to a lesser extent users changing things they should not be authorised to.

    Thanks everyone, that's a lot of great advice!

    I am worried that I might set the ownership incorrectly though!
    For example there are some rather obscure users that are supposed to have ownership of certain directories and folders.
    How would I know what's the default?

    See the link in post #2. You can automatically re-set the defaults. If you want to know what they are look in this file:
    %windir%\inf\defltbase.inf (You can see it by typing + R and then pasting in the path in bold.

    Is there a particular key you are worried about?

    Hi Adam, thanks so much for this advice! It looks like it will do what I said, but I'm just worried that it is VERY drastic.
    I have tweaked my machine quite a lot and it would be good to know exactly what this does?

    For example, why does it remove the user accounts?
    My User's folders have been moved to D: will that be affected in the reset, or will the User folders be modified in any way?
    I'm going to back them up before I do anything and will keep checking in if anyone responds.

    Hit Enter.
    After you run this, the standard user accounts may no longer appear on the logon screen when you re-start your computer or try to switch users.This occurs because standard user accounts are removed from the Users group when you reset Windows security settings.

    I have cloned my C drive, so if anything goes wrong, I'll just revert to the backup.
