Microsoft Fixes Windows Server RD Web Access Before XSLT Support Ends

Microsoft has fixed a Remote Desktop Web Access (RD Web Access) compatibility issue in Windows Server ahead of upcoming changes in Google Chrome and Microsoft Edge.

The fix comes with the November 2026 Patch Tuesday updates, including KB5131080 for Windows Server 2025.

Microsoft removes RD Web Access dependency on XSLT

RD Web Access allows users to access remote desktops and applications through a web browser. Previously, the feature relied on Extensible Stylesheet Language Transformations (XSLT) to display its web interface.

However, Google and Microsoft are removing XSLT support from Chromium-based browsers due to security concerns.

Without Microsoft’s fix, RD Web Access portals could stop loading when browsers disable XSLT.

To prevent this issue, Microsoft has changed RD Web Access to render pages on the server instead of relying on the browser. This removes its dependency on browser-side XSLT and keeps the service compatible with newer browser versions.

Windows Server administrators can remove temporary workarounds

Microsoft previously recommended temporary workarounds to keep RD Web Access functioning after browsers disable XSLT.

With the November 2026 updates installed, administrators can remove these workarounds because RD Web Access no longer requires browser-side XSLT. The fix covers Windows Server 2016, 2019, 2022, and 2025.

Administrators should install the latest security updates before Chrome 158 begins disabling XSLT support next week. This will help prevent disruptions to remote desktop access as Chromium-based browsers move away from the technology.
