Microsoft has acknowledged a significant issue affecting enterprise users trying to upgrade to Windows 11 24H2 via Windows Server Update Services (WSUS) after installing the April 2025 security updates, specifically the monthly security update KB5055528. Users with Windows 11 23H2 or 22H2 are encountering Windows Update Service errors with the code 0x80240069, preventing the download process for Windows 11 24H2 from initiating or completing. Microsoft confirmed that devices with the April security update might be unable to update via WSUS. WSUS, primarily used in enterprise settings, has been deprecated as of September 2024, but Microsoft will continue to support existing functionalities. Additionally, Microsoft is addressing a "latent code issue" that has caused some devices to upgrade to Windows 11 despite Intune policies against such upgrades.
