在这篇文章中，我们将讨论Windows 10中默认Microsoft Edge 浏览器中缺少RDWEB（远程桌面 Web 访问）中的^{(Remote Desktop Web Access)}远程桌面^{(Remote Desktop)}选项卡的问题。但在此之前，让我们先了解一下RDWEB是什么。

Microsoft 远程桌面 Web 访问^{(Microsoft Remote Desktop Web Access)}( Microsoft RDWEB Access ) 是^{(Microsoft RDWEB Access)}Windows Server 2008 R2 和Windows Server 2012中的远程桌面^(Desktop) 服务^(Services)角色，它允许用户通过开始^(Start)菜单或Web浏览器访问RemoteApp和桌面连接。^{(Desktop Connection)}

RDWEB Access还包括远程桌面 Web 连接^{(Remote Desktop Web Connection)}，它允许用户远程连接到他们拥有远程桌面访问权限^{(Remote Desktop Access)}的任何计算机的桌面。RDWEB Access必须配置为指定提供虚拟桌面和向用户显示的RemoteApp程序的源。它可以使用RemoteApp源或远程桌面连接代理^{(Remote Desktop Connection Broker)}( RD Connection Broker ) 服务器进行配置，这使用户可以访问托管在RD 虚拟化主机^{(RD Virtualization Host)} 服务器上的虚拟桌面和托管在RD 会话主机服务器上的^{(RD Session Host)}RemoteApp程序  。

RDWEB Access取代了终端^(Terminal) 服务^(Services) Web Access。

^{(Remote Desktop)}Edge中缺少RDWEB中的^(RDWEB)远程桌面选项卡

如果您正在运行远程桌面 Web 访问^{(Remote Desktop Web Access)}( RDWEB ) 或需要ActiveX控件的Web 应用程序， Edge浏览器可能无法运行 - 建议您继续使用Internet Explorer 11。

如上图所示，Edge UI （用户界面）中缺少连接到远程 PC^{(Connect to a remote PC)}选项卡，而在Internet Explorer中仍显示此选项卡。

当Internet Explorer配置为在这种情况下工作时，MsRdpClientShell – MsRdpWebAccess.dll 加载项作为ActiveX控件加载。

根据Microsoft的说法，出现此问题的原因是，根据设计，Microsoft Edge不支持ActiveX控件。

Edge 是Windows 10中的默认浏览器，提供了Internet Explorer来处理旧站点。

要解决此问题，如果您的特定网站和应用与Microsoft Edge存在兼容性问题，您可以使用企业模式^{(Enterprise Mode)} 站点列表管理器^{(Site List Manager)}将站点添加到您的企业模式站点列表^{(add sites to your Enterprise Mode Site List)}。

这使您可以继续使用Microsoft Edge作为默认浏览器，同时确保依赖Internet Explorer的站点和应用程序继续工作。

IT 管理员可以参考此Microsoft 文档^{(Microsoft Documentation)}以了解如何在其公司中使用企业模式^{(Enterprise Mode)}和企业模式站点列表管理器^{(Enterprise Mode Site List Manager)}工具。

Remote Desktop tab in RDWEB missing from Edge browser in Windows 10

In this post, we will talk about the issue of the Remote Desktop tаb in RDWEB (Remote Desktop Web Aсcess) being missing from the dеfaυlt Microsoft Edge browser in Windows 10. But before that, let us first understand what RDWEB is all about.

Microsoft Remote Desktop Web Access (Microsoft RDWEB Access) is a Remote Desktop Services role in Windows Server 2008 R2 and Windows Server 2012 that allows users to access RemoteApp and Desktop Connection through the Start menu or a Web browser.

RDWEB Access also includes Remote Desktop Web Connection, which allows users to connect remotely to the desktop of any computer where they have Remote Desktop Access. RDWEB Access must be configured to specify the source that provides the virtual desktops and RemoteApp programs that are displayed to users. It can be configured using either RemoteApp source or Remote Desktop Connection Broker (RD Connection Broker) server, which provides users access to virtual desktops hosted on RD Virtualization Host servers and RemoteApp programs hosted on RD Session Host servers.

RDWEB Access replaces Terminal Services Web Access.

Remote Desktop tab in RDWEB is missing from Edge

If you’re running Remote Desktop Web Access (RDWEB) or web apps that require ActiveX controls, the Edge browser may not work – it is recommended that you continue to use Internet Explorer 11.

As seen in the image above, the Connect to a remote PC tab is missing from the Edge UI (user interface), whereas in Internet Explorer this tab is still displayed.

When Internet Explorer is configured to work in this scenario, the MsRdpClientShell – MsRdpWebAccess.dll add-on is loaded as an ActiveX control.

According to Microsoft, this issue occurs because, by design, ActiveX controls are not supported in Microsoft Edge.

Edge is the default browser in Windows 10, with Internet Explorer provided to handle legacy sites.

To resolve this issue, if you have specific websites and apps that have compatibility issues with Microsoft Edge, you can use the Enterprise Mode Site List Manager to add sites to your Enterprise Mode Site List.

This lets you continue to use Microsoft Edge as your default browser while also making sure that sites and apps that rely on Internet Explorer continue to work.

IT administrators can refer to this Microsoft Documentation to learn how to use Enterprise Mode and the Enterprise Mode Site List Manager tool in their company.
