Microsoft Shares Temporary Fixes for Remote Desktop Problems After September Updates

Microsoft has released a Group Policy mitigation for the Remote Desktop Services connectivity issue affecting some Windows systems after the September 2026 security updates.

The mitigation targets enterprise-managed devices controlled by IT administrators and gives organizations a temporary way to address Remote Desktop failures while Microsoft works on a permanent fix.

Microsoft offers a Group Policy mitigation

Administrators can apply the new policy through Group Policy under Computer Configuration > Administrative Templates.

The mitigation can help organizations restore Remote Desktop Services functionality without removing the September security updates.

Microsoft continues to investigate the underlying issue and is developing a permanent resolution.

Restarting affected virtual machines can restore RDP access

Microsoft also recommends restarting affected virtual machines when users cannot connect through Remote Desktop Protocol.

Stopping and restarting the VM can restore RDS connectivity in some cases, although the workaround does not fix the underlying problem.

Administrators may need to repeat the process if the issue returns.

Rolling back the update can also restore Remote Desktop

Some Windows administrators have restored Remote Desktop functionality by uninstalling the affected Windows updates.

However, Microsoft does not recommend removing the updates as a long-term solution.

September’s Patch Tuesday release included 966 security fixes, so uninstalling the updates also removes those protections.

The affected updates arrived as part of the September 2026 Patch Tuesday release.

For enterprise environments, the new Group Policy mitigation offers a safer temporary option while Microsoft prepares a permanent fix.
