熟悉Windows 的用户都知道你可以在控制面板中将UAC（用户帐户控制）功能取消以避免每次安装程序都要被系统询问是否允许安装的弹窗信息最近有用户反映当你在Windows 下安装Office（部分版本）后如果想再次修改UAC设置用户在最后点击确定按钮时系统无任何反映只能取消设置对此问题微软官方给出了解决方法为
新建一记事本然后将以下内容复制粘贴进去
Windows Registry Editor Version
[HKEY_CLASSES_ROOT]
[HKEY_CLASSES_ROOT\Interface\{BBCCEBABCAA}]
@=IOleDocument
[HKEY_CLASSES_ROOT\Interface\{BBCCEBABCAA}\NumMethods]
@=
[HKEY_CLASSES_ROOT\Interface\{BBCCEBABCAA}\ProxyStubClsid]
@={AAAFEBFEFDDDCBA}
[HKEY_CLASSES_ROOT\Interface\{BBCCEBABCAA}]
@=IOleDocumentView
[HKEY_CLASSES_ROOT\Interface\{BBCCEBABCAA}\NumMethods]

[HKEY_CLASSES_ROOT\Interface\{BBCCEBABCAA}\ProxyStubClsid]

[HKEY_CLASSES_ROOT\Interface\{BBCCEBABCAA}]

[HKEY_CLASSES_ROOT\Interface\{BBCCBEBABCAA}\NumMethods]
@=
[HKEY_CLASSES_ROOT\Interface\{BBCCBEBABCAA}\ProxyStubClsid]
@={AAAFEBFEFDDDCBA}
最后将文件另存为注册表文件（如uackzreg）保存完毕后双击该文件在弹出的提示信息中选择是即可此后当你再次进行UAC设置时问题就可以解决了
