Microsoft pushes a second Windows 11 emergency update to fix Patch Tuesday chaos
Microsoft released a second emergency out-of-band update for Windows 11 (KB5078127) to fix a bug that left Outlook and cloud-based apps like OneDrive and Dropbox unusable after January Patch Tuesday; the update, targeting 24H2 and 25H2, includes fixes for unresponsiveness when opening/saving to cloud storage and follows an earlier OOB patch that resolved remote desktop and hibernation issues but briefly broke app compatibility. The rollout spans multiple Windows editions, with guidance to check the Windows release health dashboard for current status.
