How to gain access to a Registry Key and delete all subkeys

Question

I need to gain access to this Registry key and delete all sub keys, but I keep getting a permission error

 

This is the actual Registry Key that I want to remove all the sub keys from:

 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles

 

This is the code that is throwing an error:

 

If I use this code, I get a permissions Error

 

RegistryKey aRegkey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\NetworkList", true);

 

If I add the profiles Key, i Get a Null reference:

 

RegistryKey aRegkey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\NetworkList\\Profiles", true);

 

I think I have to do something like this to get security permissions . . .

 

var security = aRegkey.GetAccessControl();

var rules = security.GetAccessRules(true, true, typeof(System.Security.Principal.NTAccount));

 

Any Help would be greatly appreciated :))
