地铁风格切换为Windows8开发人员预览

介绍{S0的}
我一直在运行一段时间的Windows 8的开发人员预览版现在。由于我的笔记本电脑不支持触摸，我坚持用新的地铁风格开始菜单。老实说，这在触摸岩石！但我更喜欢经典的Windows 7开始菜单。
我上网一段时间在网上寻找一种方法来禁用新的地铁"开始"菜单和使用，而不是经典的Windows 7。许多网站指出，这是控制下HKEY_CURRENT_USER \ SOFTWARE \ MICROSOFT \ WINDOWS \ CURRENTVERSION \ Explorer中通过Windows注册表使用的RPEnabled的价值。地铁的价值是1，经典的Windows 7为0。
我决定编写的应用程序（称为"地铁风格切换？？更新的RPEnabled注册表值。在这篇文章中，我将分享我如何读/写Windows注册表值之间切换的切换，以纾缓外壳风格。背景
要迅速总结了代码: 读的RPEnabled注册表值使用Microsoft.Win32.Registry.GetValue，反映在UI上的状态更新状态标签和禁用当前状态切换按钮。因此，举例来说，如果目前的状况是地铁，那么地铁的切换，应禁用。当用户切换的状态，我使用Microsoft.Win32.Registry.SetValue更新的RPEnabled的注册表值。因此，例如，如果用户想切换回地铁，然后RPEnabled应更新，成为1。警报显示给用户，要求他们重新启动他们的计算机以使更改生效。
我写的代码上运行的Windows 8开发人员预览版，我不知道，如果它可以运行在Beta或RTM的版本。此外，你必须以管理员身份运行此应用，否则将无法更新Windows注册表（它的工作与我没有管理权限的，也许是因为我的管理员{S1}，更好地以管理员身份运行）。请注意，Windows可能会问你，如果你还没有激活运行时使用的Windows功能激活SP1的安装微软NET Framework 3.5中。地铁风格
