Microsoft: We're continuing our analysis of system logs and reported affected user details to determine our next steps towards remediation.

If you connect to a terminal server, you may run into these issues.

Microsoft: We've received reports of this problem occurring on Windows Server 2019 devices and have updated our Title and User impact fields to reflect our updated understanding of this impact. Regarding the status of our investigation, we've identified a recent Office update that integrates React Native framework to support certain features in Microsoft 365 applications has introduced a problem that's causing the impact.

Microsoft: We've implemented a change to mitigate the impact for users on Windows Server 2016 devices, by reverting to version 2411, which isn't affected, and we're reaching out to some affected users to confirm that this resolves the problem. We're determining if the same method can be used to mitigate the issue for users on Windows Server 2019 devices, or if another mitigation strategy is needed.

Microsoft: We've confirmed with some affected users that impact has been mitigated for those on Windows Server 2016 devices after receiving version 2411. We anticipate that it may take up to 24 hours for automated update systems to pick up the change. In parallel, we're continuing to assess the best method for remediating the issue on Windows Server 2019 devices.

From Microsoft: The revert to version 2411 is in progress and we've received confirmation from some affected users that their Windows Server 2016 and 2019 devices are working as expected. We expect that it may take up to 24 hours for automated systems to pick up the change. We'll continue monitoring the revert progress to verify that the impact is remediated.

Microsoft: We've completed the initial stages of the rollback process to Version 2411. We're continuing to monitor this to ensure it has the desired effect of remediating impact.
