如何清除 IE WebBrowser Control cookie

Question

我已经尝试过 INTERNET_OPTION_END_BROWSER_SESSION ，但是这不会删除 cookie 我发现的唯一方法是使用 RunDll32.exe InetCpl 删除 IE 浏览器 cookie 本身。 cpl,ClearMyTracksByProcess 2. 这工作得很好但是这会打开 IE 清除历史对话框 有没有其他方法可以删除清除 WebBrowser Control cookie

Answer 1

不要进入这么复杂的东西。只需下载 ccleaner 或打开它（如果您已经拥有），然后转到自定义清理 -> 应用程序并勾选标题 Internet Explorer ->“Cookie 和其他站点数据”下的复选框

如果要删除或禁用 IE，请转到设置-> 或控制面板（如果您没有 Windows 10 操作系统），然后转到程序和功能 -> 卸载程序 -> 启用某些 Windows 功能 -> 取消勾选复选框“ Internet Explorer 9 或 11（无论您拥有哪个版本）” 希望你喜欢这个答案并为你工作
