UWP应用是类似于沙盒应用，无法使用系统的代理，如果想要用google登陆UWP应用，会由于无法使用系统搭理而代理登陆失败。

解决方法

把下面这段代码复制到记事本中，后缀名改成.vbs，然后双击运行

    Set ws = WScript.CreateObject("wscript.shell")  
    app = ws.ExpandEnvironmentStrings("%USERPROFILE%\AppData\Local\Packages")  
    Set fso = WScript.CreateObject("scripting.filesystemobject")  
    Set fs = fso.GetFolder(app).SubFolders  
    Set bat = fso.createtextfile(ws.ExpandEnvironmentStrings("%TEMP%\WindowsAppProxyAccess.bat"))  
    For Each f In fs  
        bat.WriteLine ("CheckNetIsolation.exe LoopbackExempt -a -n=" & f.name)  
    Next  
    bat.WriteLine ("del %0")  
    CreateObject("Shell.Application").ShellExecute ws.ExpandEnvironmentStrings("%TEMP%\WindowsAppProxyAccess.bat"),"","","runas",1
