Requested Registry Access Is Not Allowed

Requested registry access is not allowed

app.manifest should be like this:

<?xml version="1.0" encoding="utf-8"?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <assemblyIdentity version="1.0.0.0" name="MyApplication.app" />
   <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
      <security>
         <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
            <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
         </requestedPrivileges>
      </security>
   </trustInfo>
</asmv1:assembly>

Requested registry access is not allowed. even with signed exe and admin Privileged in manifest

I found the problem but I don't know why access to this address is impossible

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\Properties

Registry Error on Regedit
Visual Studio Debug

I fixed my code with regex

static string GetDeviceGuid()
    {
        const string AdapterKey = "SYSTEM\\CurrentControlSet\\Control\\Class\\{4D36E972-E325-11CE-BFC1-08002BE10318}";
        RegistryKey regAdapters = Registry.LocalMachine.OpenSubKey(AdapterKey);
        string[] keyNames = regAdapters.GetSubKeyNames();
        foreach (string x in keyNames) {
            Console.WriteLine(x);
        }
        string devGuid = "";
        Regex rx = new Regex(@"\d{4}",
      RegexOptions.Compiled | RegexOptions.IgnoreCase);
        foreach (string x in keyNames)
        {
            if (!rx.IsMatch(x)) {
                continue;
            } 
            RegistryKey regAdapter = regAdapters.OpenSubKey(x);
            object id = regAdapter.GetValue("ComponentId");
            if (id != null && id.ToString() == "tap0901") devGuid = regAdapter.GetValue("NetCfgInstanceId").ToString();
        }
        return devGuid;
    }

Run as administrator, but still requested registry access is not allowed

If you run regedit and navigate to the key that you are trying to access with your script, you can right click on it and view the permissions. You can see on that key what permissions Administrator has (Full Control, Read, Special Permissions)
