UPDATE 9/25:


 Windows Insider Blog:

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27950 to the Canary Channel.

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.

[Settings]

  • Advanced Settings will revert to the previous “For Developers” experience after updating to this build. This change will come back soon.

Fixes

[General]

  • Fixed an issue causing some Insiders to experience a rollback attempting to install the latest build with either an 0xC1900101-0x20017 error or 0xC1900101-0x30017 error.

[Taskbar and System Tray]

  • Fixed an issue which could cause the app preview windows in the taskbar to become misaligned (away from the app icon you’d clicked / hovered over) after a display resolution change.

[File Explorer]

  • Fixed an issue where interacting with the context menu in File Explorer could lead to the body of File Explorer becoming unresponsive to clicks.
  • Fixed an issue which could lead to certain apps hanging when launching the Open or Save Dialog.
  • Fixed an issue where with certain apps installed, when you right clicked you may see the context menu unexpectedly switch back and forth with each right click between the normal initial view and “Show more options”.

[Graphics]

  • Fixed an which was causing some Insiders to experience screen flickers when using the browser (and potentially other scenarios) in the latest Canary builds.

Hi folks
Another issue again related to languages in the Canary version (Languages that have to be added afterwords as the base full language pack doesn't exist in Windows) fails to install on screen keyboard correctly in the language selected for some languages.

Works perfectly on the standard 25H2 update

I understand that probably only 2 if that of the probable 100,000 Indian developers understand some of these minor languages - but it's easy enough these days

Provided you can separate a lot of the apps from the GUI you could establish basic screen definitions and then set up something like a Data Dictionary for the text elements / labels for the screen objects. Back ages ago when I actually did a bit of programming I think this type of technique was called MVC. (Model View controller).

I believe multi language versions of SAP (Huge world wide Software company) use this type of approach so it's relatively simple to have multi language versions in almost any existing language on the planet with only minor modifications from the base product.

In SAP works like this :

Hi there

@cute two
I know -- I was trying to show problems with the Canary build (latest) compared with what is running OK in the standard 25H2 build. Language issues that were WORKING now aren't !!!
