RDS HTML5 webclient update 1.0.1 - fixing the AltGr issues

RDS HTML5 webclient update 1.0.1 - fixing the AltGr issues


With the launch of the HTML5 Webclient for Remote Desktop Services (RDS) 2016, Microsoft has released a great feature. Because all existing software can be used inside any browser, without rewriting the application. We wrote an introduction about the Webclient, which you can find here: https://blog.aspex.be/en/microsoft-remote-desktop-client-first-look

Public Preview to GA

In July, when the Webclient went from Public Preview to GA (version 1.0.0), several updates were included in this release. Some highlights:

  • Single Sign On (SSO) experience for the users
  • Time Zone Redirection
  • Improved sign-in experience
  • Improved error messages & handling
  • Copy&Paste text through the clipboard using Ctrl+C & Ctrl-V
  • etc

Update 1.0.1 fixing the AltGr issues

Despite all these great features, there was still an big issue, especially for European users: the AltGr keystrokes did not work correctly (or at all). So for most European keyboards, you could not type @, , { or any character using the AltGr key.

But now, Microsoft freshly released update 1.0.1 for the Webclient, fixing this bug. (at the time of writing this blog, the release notes are not yet online, but you should be able to find them here: What's new for the Remote Desktop web client?)

Typing the characters

I installed the update on my existing deployment and I'm able to type all these characters inside the Webclient!

How to update?

When you want to update your current Webclient, you just have to follow these simple steps:

  • Open an elevated PowerShell prompt on the RD Web Access server
  • Download the latest available version of the web cient
  • If you want to test the update first, you can Publish the client to Test slot in your deployment using this cmdlet:
    Publish-RDWebClientPackage -Type Test -Latest

    You can access this Test deployment using this url: https://«Your-Deployment-FQDN»/RDWeb/webclient-test/index.html

  • If you tested the update and want to put it online, you can use this cmdlet:
    Publish-RDWebClientPackage -Type Production -Latest


That's it, your deployment is updated to version 1.0.1, with all bugfixes, including the AltGr fix.
