Fixes in this Build
File Explorer
- Fixed an issue which could cause File Explorer to show a Catastrophic Error (0x8000FFFF) when extracting large (1.5gb+) archive files.
- Fixed an issue which could cause an old white toolbar to randomly appear in File Explorer sometimes.
Display and Graphics
- Fixed a recent issue which was causing some videos and games to be unexpectedly red.
- Fixed an issue where apps and browsers could have partially stuck onscreen content when other maximized / full screen apps were updating in the background. This may have been noticeable particularly when trying to scroll the window content, as only some parts would update.
- We’ve improved the performance when apps query monitors for their full list of supported modes. When this happens could lead to a momentary stutter on very high-resolution monitors, and this work should help prevent and reduce stuttering in these scenarios.
Windows Update
- Fixed an issue which could lead to updates failing to install with error 0x800f0983.
Other
- Fixed a hang which could impact Outlook in recent builds, where if prompted for your credentials, you wouldn’t be able to bring the pop up to the foreground and it would go unresponsive.
- Fixed an issue which was causing Remote Credential Guard scenarios between the latest Windows 11 builds and Server 2022 (and below) to fail.
- Fixed an issue which could cause the print preview screen to stop responding in Chromium-based browsers.
