Question

Here's my code: 这是我的代码：

RegistryKey reg = Registry.LocalMachine;
var HKLM = reg.OpenSubKey(@"Software\\Microsoft\\Cryptography");
HKLM.DeleteValue("MachineGuid");

Problem: Even when I run it as an administrator; 问题：即使我以管理员身份运行它； it will just give me an error that saying: 这只会给我一个错误，说：

Cannot write to the registry key. 无法写入注册表项。

I can't delete anything in the local machine folder. 我无法删除本地计算机文件夹中的任何内容。

Answer 1

如果要进行写访问，则需要将RegistryKey指定为可写的。

Registry.LocalMachine.OpenSubKey(@"Software\\Microsoft\\Cryptography",true);
