Microsoft has released cumulative update KB5095128 (Build 28020.2380) for Windows 11 version 26H1, intended for participants in the Windows Insider Program on the Beta channel. This patch includes a small set of general improvements and fixes aimed at enhancing the overall quality and stability of the operating system.
- Free upgrade to Windows 11 Pro for Education. Insiders in K-12 educational environments can now perform a simple transition from Windows 11 Home to Windows 11 Pro for Education at no additional cost. This allows educational institutions to purchase devices with the Home edition, upgrade them, and bring them under centralized management. To initiate the process, you must sign in with a local account, run Clipupgrade.exe as an administrator, and then authenticate using a K-12 organization account. The upgrade is one-way; reverting to Windows 11 Home without a clean reinstallation of the system is not supported. Feedback can be submitted in the Feedback Hub (WIN + F) under Install and Update > Windows Installation.
- Fix for File Explorer. Resolved an issue where the OneDrive shortcut in File Explorer would stop functioning when File Explorer was launched with administrator privileges.
- Fix for Outlook. Addressed a problem where the Outlook application could become unresponsive to the close window button.
To install update KB5095128, go to Settings > Windows Update and click the Check for updates button. A system reboot is required to complete the installation procedure. As this build is intended for Insiders, the update is only available on the Beta channel.
It should be noted that the education edition upgrade feature is exclusively relevant for K-12 institutions and requires verification of eligibility through a work account.
