Changes and Improvements gradually being rolled out*
[Print Drivers]
- The Internet Protocol Print driver (prnms012) has new hardware IDs (HWIDs) in preparation for upcoming changes in printer driver ranking order. See our third-party driver deprecation timeline: End of Servicing Plan for Third-Party Printer Drivers on Windows - Windows drivers | Microsoft Learn.
[Start menu]
- Improved detection of clicks at the leftmost edge of the taskbar to invoke start menu when the taskbar icons are set to left aligned.
[Other]
- Removed unexpected error that was showing when opening Group Policy Editor in the last couple Insider flights.
- We have updated Times New Roman to improve support for combining diacritical marks across the Greek and Cyrillic Unicode ranges. If you notice any positioning issues with these diacritical marks, let us know by filing feedback under Desktop Environment > Font Installation and Preview in the Feedback Hub – preferably with details about the specific Unicode character, and a screenshot highlighting the expected position.
Reminders for Windows Insiders in the Beta Channel (Soon transitioning to the new Beta experience)
- Updates are based on Windows 11, version 25H2 via an enablement package (Build 26220.8283).
- Many features are rolled out using Controlled Feature Rollout technology, starting with a subset of Insiders and ramping up over time as we monitor feedback to see how they land before pushing them out to everyone in this channel.
- The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
- For Windows Insiders who want to be the first to get features gradually rolled out to you, you can turn ON the toggle to get the latest updates as they are available via Settings > Windows Update*. Users can also use the Feature flags settings page to enable certain features. Over time, we will increase the rollouts of features to everyone with the toggle turned on. Should you keep this toggle off, new features will gradually be rolled out to your PC over time once they are ready.
- Features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they’re ready.
- Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.
- Check out Flight Hub for a complete look at what build is in which Insider channel.

Generally, when you see an error, it means that the OS saw the error and corrected it long before it could become critical. Microsoft is well-aware of them.
