有人可以找出为什么PKEY_EdgeGesture_DisableTouchWhenFullscreen不再适用于Win 10周年更新以及如何解决问题？
目前我正在使用here中的Ron Schuler代码在我的应用中禁用边缘手势。
它在Win 10 RTM和Win 10 November Update（1151）中运行良好，但不再适用于Win 10周年更新。
并且不再有效，我的意思是没有错误或异常，只需调用该方法就不会禁用边缘手势。
不，重写Win 10 Kiosk模式的应用程序（例如，使其成为Metro或Universal App）不是解决方案！
由于我是c＃开发人员而不是本地c ++开发者，我不知道如何解决这个问题...
我在c＃中的代码：

答案 0 :(得分：-1)
我找到了一个解决方法：
如何在Windows 10中禁用触摸屏边缘滑动（仅限周年纪念版）
1）打开注册表编辑器 2）转到以下注册表项：
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\EdgeUI
你可能没有这样的密钥，所以只需创建它。
3）创建一个名为AllowEdgeSwipe的新32位DWORD值。将其值数据保留为0（零）以禁用边缘滑动
4）要应用更改，请重新启动Windows 10.
这当然会永久禁用边缘滑动。之前的PKEY_EdgeGesture_DisableTouchWhenFullscreen方法仅允许在您的应用运行时禁用边缘滑动...
