Remote Desktop Connection无法全屏解决方案

Sometimes, Remote Desktop Connection总是一个窗口，不自动全屏，任务栏不能自动隐藏起来，要拖动滚动条，并且无法使用常用WINDOWS快捷键，for instance, 想用alt+tab切换远程服务器的几个窗口，但是却切换了本地计算机的窗口，非常不便，以下是解决方法：
First, Open the control panel, then open the folder options, check Show hidden files,folder,and drivers.
Secondly, open My documents, you can find a hidden file 'default.tdp', delete it.
Try it again, the results achieved.
