我尝试将注册表子项及其相应的值写入注册表,如下所示:
Microsoft.Win32.RegistryKey mykey;
mykey = Microsoft.Win32.Registry.CurrentUser.CreateSubKey("Software\\Microsoft\\Windows\\Muhil Software");
mykey.SetValue("Muhil", "TEST");
mykey.close();

正如你所看到的,我曾经CurrentUser将值写入HKEY_CURRENT_USER,其中没有任何内容HKEY_CURRENT_USER。然后我检查了子项HKEY_USERS,发现密钥写在那里。
您的安装程序不会在登录的用户会话下运行,而是在本地系统会话下运行。这解释了为什么这些HKCU指向另一个注册表配置单元。
为了打开登录用户的注册表项,您需要打开此注册表项HKU/<LOGGED_ON_USER_SID>。您可以通过 Windows 会话 API 获取此 SID(安全标识符)。
由于用户 SID,您可以使用Microsoft.Win32.Registry.Users而不是打开正确的用户密钥。Microsoft.Win32.Registry.CurrentUser
您可以在 stackoverflow 上找到有关如何获取当前登录 SID 的多个主题,例如How to get a Unique ID for the current user's logon session in windows - c#
更新:能够获取登录用户 SID 字符串的示例代码,它只能在系统会话中工作,因为它需要特殊权限SE_TCB_NAME。为了简单起见,没有错误处理

Microsoft.Win32.RegistryKey mykey;
mykey = Microsoft.Win32.Registry.Users.CreateSubKey(GetLoggedOnUserSID() + "\\Software\\Microsoft\\Windows\\Muhil Software");
mykey.SetValue("Muhil", "TEST");
mykey.Close();
