Hello all, yesterday Microsoft released not only Windows 11 Insider Preview Build 27934 to the Canary Channel, but also a build to de Dev and Beta Channel.
Upgrades went smooth and fast on all my Canary devices (added a Surface Laptop 13in to the pool)
Happy Upgrades!
Changes and Improvements
[General]
- This update includes a small set of general improvements and fixes that improve the overall experience for Insiders running this build on their PCs.
Fixes
[Windowing]
- Fixed an issue causing an increase in DWM crashes in the previous build (which could lead to you seeing a black flash).
[Other]
- Fixed an issue in the last few builds where if you launched cmd non-elevated from the Run dialog, it might open in Windows Console Host rather than Windows Terminal even if Windows Terminal was your default terminal app.
- Fixed an underlying issue which could lead to certain UWP apps crashing when scrolling in the previous build.
Known issues
[General]
- We’re investigating reports that Settings > System > Storage > Temporary files is getting stuck when scanning files. We are also investigating previous Windows Installations also not showing.
[File Explorer]
- In dark mode, the red color used for a low space drive in This PC may be unexpectedly light colored in this build. Some of the other colors may also be incorrect, including that black is used for space remaining instead of a more visible color.
[Reset & Recovery]
- [NEW] The “Reset this PC” option Settings > System > Recovery will not work on this build. This issue will be fixed in the next Canary Channel flight. Should you need to reset your PC, you can roll back to the previous build and do a PC reset then.
