value not update in Registry at given path in C#

string path = @"Software\Microsoft\Windows NT\CurrentVersion\Windows\"; RegistryKey myKey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(path, true); myKey.SetValue("USERProcessHandleQuota", 50000, RegistryValueKind.DWord); myKey.Close();

instead of given path value update at :- @"Software\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows\";

What I have tried:

@"Software\Microsoft\Windows NT\CurrentVersion\Windows\"

I think you need administrator privilege to update HKLM entries.

There are lot of options for failure... https://docs.microsoft.com/en-us/dotnet/api/microsoft.win32.registrykey.setvalue?view=netframework-4.7
Check yours against the list...

It has to do with your application. If your application is 32 bit, then it gets redirected to Wow32 instead. If you still want to manipulate the non Wow32 values though, you have to specify the RegistryView.
