Answer 1

您可以使用：

import _winreg
_winreg.DisableReflectionKey(_winreg.HKEY_LOCAL_MACHINE)
# do stuff here
_winreg.EnableReflectionKey(_winreg.HKEY_LOCAL_MACHINE)

但是，这只适用于python2.6及更高版本。在

winreg中关于反射的关键特性的文档很少（而且缺少一些零碎的内容）。您确实需要this patch，但在应用它并使用这些修复程序制作新的Python微版本之前，至少可以根据补丁添加的文档尝试DisableReflectionKeyetc路径（以下是第一个）：

+.. function:: DisableReflectionKey(key)
+   
+   Disables registry reflection for 32-bit processes running on a 64-bit
+   Operating System.
+   
+   *key* is an already open key, or one of the predefined :const:`HKEY_\*`
+   constants.
+   
+   Will generally raise :exc:`NotImplemented` if executed on a 32-bit
+   Operating System.

+   If the key is not on the reflection list, the function succeeds but has no
+   effect. Disabling reflection for a key does not affect reflection of any
+   subkeys.

+
+.. function:: EnableReflectionKey(key)
+
+   Restores registry reflection for the specified disabled key.
+   
+   *key* is an already open key, or one of the predefined :const:`HKEY_\*`
+   constants.
+
+   Will generally raise :exc:`NotImplemented` if executed on a 32-bit
+   Operating System.
+   
+   Restoring reflection for a key does not affect reflection of any subkeys.
+
+
+.. function:: QueryReflectionKey(key)
+
+   Determines the reflection state for the specified key.
+   
+   *key* is an already open key, or one of the predefined :const:`HKEY_\*`
+   constants.
+   
+   Returns ``True`` if reflection is disabled.
+
+   Will generally raise :exc:`NotImplemented` if executed on a 32-bit
+   Operating System.
