Windows 11 Insider Preview Build 25126 Releases

Microsoft pushed Windows 11 Insider Preview Build 25126 to users in the development channel recently. The focus of this update is still to fix various blue screens of death. In terms of new features, Microsoft has improved the account page to support more Office licenses, such as related licenses for Office 2019 and Office 2021. In addition, Microsoft emphasized that relevant bug fixes may be pushed to the stable version through cumulative updates over time to improve system stability.

After logging in to Windows 11 with a Microsoft account, the Microsoft 365 subscription and expiration time will be automatically displayed in the account settings. In this update, Microsoft supports querying more Office product licenses, such as Microsoft Office 2019 and Microsoft Office 2021. After the user clicks to view the details, they can jump to the Microsoft page to download the installation program. Each product component is different, so the displayed product authorization is also different.
