About this tag
KB5068221 is an unscheduled, out-of-band cumulative update for Windows 11, including version 24H2, released by Microsoft to fix a high-impact compatibility regression where Microsoft Office failed when delivered via Microsoft Application Virtualization (App-V). The update restores App-V Office stability and includes September's security fixes and a servicing-stack update. However, administrators must address a separate SMBv1/NetBIOS connectivity caveat before broad rollout. This tag covers discussions about the patch's purpose, its emergency nature, and the specific SMBv1 workaround required.
