What the notice says

Microsoft’s text, safely structured

Updated November 12, 2026: We are informing regarding November updates for Windows Server which address this change.

What and why

The Remote Desktop Web Access (RD Web Access) experience included with Windows Server relies on Extensible Stylesheet Language Transformations (XSLT) to render its web interface. Across the industry, browsers are moving away from XSLT, with Chromium-based and other browsers disabling XSLT support in the short term.

As browsers disable XSLT, the RD Web Access experience included with Windows Server will no longer render as expected. To address this, the November 2026 Windows security update for supported versions of Windows Server provides an updated RD Web Access experience.

Rollout schedule

The November 2026 Windows security update was released November 10, 2026. It is available now for supported versions of Windows Server. This change is also included in subsequent updates.

Impact on your organization

Organizations that have deployed the RD Web Access experience included with Windows Server are affected. After XSLT support is disabled in a browser, users who open RD Web Access with that browser might encounter a page that fails to render as expected. As a result, users might be unable to access remote resources.

Action required/recommendations

Install the latest Windows security update for Windows Server to continue using the RD Web Access experience included in Windows Server. You can review details at KB5130994: RD Web Access fails to load when XSLT is disabled in Microsoft Edge or Google Chrome. If you have customizations applied, please also follow additional guidance here: RD Web Access customizations.

Compliance considerations

No compliance considerations are identified. Review as appropriate for your organization.
