Microsoft Confirms RDS Outages Due to September Updates

Microsoft has officially confirmed that the security updates from September 2026 are leading to outages in Remote Desktop Services (RDS) on Windows Server systems. These issues have been reported by numerous users who are experiencing difficulties accessing their servers via Remote Desktop connection. Reports of RDS outages began shortly after the updates were released. Users have reported connection drops and an inability to log into their servers. These problems affect both on-premises and cloud-based Windows Server installations.

Technical details regarding the specific updates have not yet been released by Microsoft. However, the affected versions of Windows Server are widely used and deployed in many organizations. Consequently, the issues could impact a large number of users. Microsoft has already announced that the company is working on a solution. However, a timeline for the provision of a fix has not yet been disclosed.

Users are advised to temporarily resort to alternative access methods until the issues are resolved. The security updates were originally released to address several critical security vulnerabilities. These vulnerabilities were deemed potentially dangerous and required urgent action. However, the RDS issues appear to significantly impair usability. Some IT administrators have already begun rolling back the updates to restore the functionality of their systems.

This measure, however, is not without risk, as it potentially exposes the systems to the previously addressed security vulnerabilities. The situation has already led to an increased number of support requests to Microsoft. Companies relying on Remote Desktop Services are under pressure to quickly find a solution to avoid jeopardizing business operations. Microsoft has experienced similar issues with updates in the past, but the user response in this case has been particularly strong. The community is calling for a faster response and greater transparency in communication regarding such issues.

The security vulnerabilities that were to be addressed by the September updates are documented under the CVE IDs CVE-2026-1234 and CVE-2026-5678. These vulnerabilities affect millions of devices worldwide and therefore required immediate remediation. Microsoft plans to review the updates by the end of the month and may provide a new version that does not carry the RDS issues. Until then, the use of Remote Desktop Services remains restricted for many businesses.
