Microsoft released cumulative update KB5083781 (Build 26220.8283) for Windows 11 version 25H2 for Insiders on the Beta Channel. This update includes several improvements and fixes aimed at increasing system stability and supporting peripheral devices.
- Printer drivers. The Internet Protocol Print driver (prnms012) received new hardware identifiers (HWID). This is done in preparation for upcoming changes to the printer driver priority order. Details about the end of servicing for third-party printer drivers are available in Microsoft documentation: End of Servicing Plan for Third-Party Printer Drivers on Windows.
- Start menu. Improved recognition of clicks on the far left edge of the taskbar to open the Start menu in cases where taskbar icons are left-aligned.
- Group Policy Editor. Fixed an unexpected error that occurred when opening the Group Policy Editor in several recent Insider builds.
- Times New Roman font. Updated the Times New Roman font — improved support for combining diacritical marks in the Greek and Cyrillic Unicode ranges.
If you notice issues with diacritical mark positioning in the Times New Roman font, report it through the Feedback Hub under Desktop Environment > Font installation and preview — preferably with the specific Unicode character and a screenshot showing the expected position of the mark. It is also important to note that features and functionalities included in Beta Channel builds may never appear in the final release, as Microsoft actively tests different concepts and gathers feedback. Features may change, be removed, or be replaced and never leave the Windows Insider program. Some of them may appear in future versions of Windows when fully ready.
To install the update, go to Settings > Windows Update and click Check for updates. A computer restart will be required to complete the installation.
