Question

有人可以为我解释这个奇怪的结果吗？

在linqPad中获得以下代码

Microsoft.Win32.Registry.CurrentUser.OpenSubKey(@"Software\Microsoft").Dump();
Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"Software\Microsoft").Dump();

查看进程监视器时，它看起来像这样：

RegQueryKey    HKU\S-1-5-21-...   
RegOpenKey     HKU\S-1-5-21-...\Software\Microsoft   
RegSetInfoKey  HKU\S-1-5-21-...\Software\Microsoft   
RegQueryKey    HKU\S-1-5-21-...\Software\Microsoft   
RegQueryKey    HKU\S-1-5-21-...\Software\Microsoft   
RegQueryKey    HKLM   
RegOpenKey     HKLM\Software\Wow6432Node\Microsoft   
RegSetInfoKey  HKLM\SOFTWARE\Wow6432Node\Microsoft   
RegQueryKey    HKLM\SOFTWARE\Wow6432Node\Microsoft   
RegQueryKey    HKLM\SOFTWARE\Wow6432Node\Microsoft

我的问题是：
为什么Registry.CurrentUser访问64位和Registry.LocalMachine 32位？

（还有，为什么Registry.CurrentUser访问HKU\S-..而不是HKCU）

使用Windows 7,64位，.Net 3.5，LINQPad.exe *32

如果您查看MSDN documentation，它表示HKCU \ Software \ Classes通过WOW64重定向重定向，但不是整个HKCU \ Software密钥。

HKEY_CURRENT_USER           Shared          Shared
    SOFTWARE                Shared          Shared
        Classes             Shared          Redirected and reflected
            Appid           Shared          Redirected and reflected with one exception: the DllSurrogate and DllSurrogateExecutable registry values are not reflected if their value is an empty string.
            CLSID           Redirected      Redirected and reflected
            DirectShow      Redirected      Redirected and reflected
            Interface       Redirected      Redirected and reflected
            Media Type      Redirected      Redirected and reflected
            MediaFoundation Redirected      Redirected and reflected

Registry.CurrentUser和64位
