Originating KB URL: https://support.microsoft.com/en-us/topic/5049981 Originating KB Release Date: 2025-01-14T10:00:00-08:00 Originating Build: 19045.30000 Resolved KB URL: All Updates: ------------------------------------------------------ January 14, 2025 18:04 PM Devices which have certain Citrix components installed might be unable to complete installation of the January 2025 Windows security update (KB5049981 (https://support.microsoft.com/help/5049981)). This issue was observed on devices with Citrix Session Recording Agent (SRA) (https://docs.citrix.com/en-us/session-recording/current-release/install-upgrade-uninstall.html) version 2411. The 2411 version of this<s> </s>application was released in December 2024. Affected devices might initially download and apply the January 2025 Windows security update correctly, such as via the Windows Update page in Settings. However, when restarting the device to complete the update installation, an error message with text similar to “Something didn’t go as planned. No need to worry – undoing changes” appears. The device will then revert to the Windows updates previously present on the device. This issue likely affects a limited number of organizations, as version 2411 of Citrix SRA is a new version. Home users are not expected to be affected by this issue. Workaround: Citrix has documented issue, including a workaround which can be performed prior to installing the January 2025 Windows security update. For details, see Microsoft's January Security Update Fails/Reverts on a machine with 2411 Session Recording Agent (https://support.citrix.com/s/article/CTX692505-microsofts-january-security-update-failsreverts-on-a-machine-with-2411-session-recording-agent). Next steps: Microsoft is working with Citrix to address this issue and will update this documentation once a resolution is available.
