Microsoft released a preview update designated as C-release under KB5095093, along with dynamic updates KB5102558 and KB5095615, focusing on setup and recovery enhancements for Windows 11. A new Out of Box Experience (OOBE) update has been introduced for Windows 11 versions 25H2 and 24H2. The OOBE is the initial setup phase after Windows installation. The cumulative update KB5095189, dated June 23, 2026, enhances the OOBE process for these versions. OOBE updates are installed automatically for users with an active internet connection. During OOBE, Windows automatically downloads and installs critical driver updates and zero-day patches once connected to a network. If a newer version of Windows is available, it may also be downloaded and installed during the OOBE process, ensuring the device has the latest security measures and features upon completion of the setup.
