Windows updates during OOBE

Critical driver updates, and critical Windows zero-day patch (ZDP) updates, will begin downloading automatically during OOBE after the user has connected to a network. The user can't opt-out of these critical updates as they are required for the device to operate properly. Windows will alert the user that the device is checking for, and applying, the updates.

If a newer version of Windows is available than the version that shipped with the device, depending on OS Build, a user may receive latest Windows Updates as one of the last sections of the OOBE. The Windows update will be downloaded and installed during the OOBE. This process may take 30 minutes or more: the size of the update, the user's network conditions, and the hardware capabilities of the device will determine the download and installation time. During this process, the user is encouraged to keep the PC on and plugged in. OOBE will reboot the PC after download and installation to complete the update.
