How to change the owner of a registry key ?

[Ky Nam]

Hi I want to open a registry key for changing the owner , user has admin right

    Dim User As String = Environment.UserDomainName & "\\" & Environment.UserName

    Dim K As Microsoft.Win32.RegistryKey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Component Based Servicing", RegistryKeyPermissionCheck.Default, Security.AccessControl.RegistryRights.TakeOwnership)

    Dim RS As Security.AccessControl.RegistrySecurity = K.GetAccessControl

    Dim NTA As New Security.Principal.NTAccount(User)

    RS.SetOwner(NTA)

    K.SetAccessControl(RS)

But .NET throws an exception : Requested registry access is not allowed I can open Regedit.exe and take registry key's owner ship , why this code doesn't work ?

You haven't opened the key with the appropriate access and permissions. You've opened it for Read, but not Write. Try changing the OpenSubKey line to:

...LocalMachine.OpenSubKey("...", RegistryKeyPermissionCheck.ReadWriteSubTree, Security.AccessControl.RegistryRights.FullControl)
