title: Registry - Create Key - Security
body: <p>I'm considering creating a key under HKEY_LOCAL_MACHINE.  I've read the MDSN and kind of understand what to do but am concerned about the Registry Security business.  I want any user on the system to be able to access the key.  Do I need to specify something in the  LPSECURITY_ATTRIBUTES parameter of the RegCreateKeyEx call?  If so what?  Under the description of that parameter, there is a link to SECURITY_ATTRIBUTES where it says "This is not the same as granting access to everyone by assigning a NULL discretionary access control list (DACL)." But I can't find out exactly what that means.  Can anyone help?</p>
