Setting HKLM Regkey permissions with c# on Win 10 1803
I am trying to alter the permissions on a regkey under HKLMSOFTWARE using c#. I want to maintain the permissions that are already present on the key.
Here is the code that I'am testing with (I know that this needs elevated rights):
using Microsoft.Win32;
using System.Security.AccessControl;
using System.Security.Principal;
namespace RegKeyPermissions
{
class Program
{
static void Main(string args)
{
SecurityIdentifier sident = new SecurityIdentifier(WellKnownSidType.BuiltinUsersSid, null);
string groupname = sident.Translate(typeof(NTAccount)).Value;
using (var hklm64 = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64))
{
using (var testkey = hklm64.CreateSubKey(@"SOFTWARETest1Test2", true))
{
var regsec = testkey.GetAccessControl(AccessControlSections.All);
var sddl1 = regsec.GetSecurityDescriptorSddlForm(AccessControlSections.All);
var regsecrule = new RegistryAccessRule(sident,
RegistryRights.FullControl,
InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit,
PropagationFlags.None,
AccessControlType.Allow);
regsec.AddAccessRule(regsecrule);
var sddl2 = regsec.GetSecurityDescriptorSddlForm(AccessControlSections.All);
testkey.SetAccessControl(regsec);
regsec = testkey.GetAccessControl(AccessControlSections.All);
var sddl3 = regsec.GetSecurityDescriptorSddlForm(AccessControlSections.All);
}
}
}
}
}
The problem is that when I open regedit to check the permissions it is telling me that the access rules are in the wrong order. I tried to look at the sddl and the problem seems to be in SetAccessControl.
I didn't find any useful information in the msdn that I am doing something wrong here. SetAccessControl should add it in the correct order.
Maybe someone here finds an error?
As a sidenote doing it with some powershell the ordering is done correctly.
