Microsoft has confirmed a widespread issue in Windows Server Update Services (WSUS) that prevents organizations from syncing with Microsoft Update and deploying the latest Windows updates.

Windows Server Update Services (WSUS) is a Microsoft product that allows businesses to manage and distribute Windows updates to computers within their network.

By default, WSUS synchronizes with Microsoft Update servers once a day, when it downloads the latest metadata on available Windows updates. Admins can change the frequency if they wish in the settings.
