Windows 11 Insiders in the Dev Channel are in for a treat this week with the rollout of build 26120.1930. This latest update introduces a variety of intriguing enhancements, including the ability to remap the Copilot key, a new simplified Chinese font, and notable improvements to Windows Sandbox.
Key Changes and Improvements
The following changes are gradually being made available to Dev Insiders who have activated the “Get the latest features as soon as they are available” toggle:
General
- This update brings a collection of general improvements and fixes aimed at enhancing the overall experience for Insiders using this build on their PCs.
Fonts
- A new simplified Chinese font, Simsun-ExtG, has been introduced, featuring 9,753 ideographs that support Unicode Extensions G, H, and I. Among these is the highly sought-after character for Biangbiang noodles (U+30EDD), noted for being one of the most complex Chinese characters. However, it is important to note that some applications may not yet support these new extension characters.
- Unicode range G: 30000-3134A (4,939 chars)
- Unicode range H: 31350-323AF (4,192 chars)
- Unicode range I: 2EBF0-2EE5D (622 chars)
Windows Sandbox
- The new Windows Sandbox Client Preview, which began its rollout with Build 26120.1843, is now accessible to all Insiders in the Dev Channel.
Additionally, the following updates are being gradually rolled out to all Dev Insiders:
Settings
- Users can now configure the Copilot key to launch an MSIX packaged and signed app, ensuring that it meets security and privacy standards. Until a different experience is selected, the key will continue to launch Copilot on devices with the Copilot app installed. This setting can be adjusted via Settings > Personalization > Text input. Note that if your keyboard does not feature a Copilot key, this adjustment will have no effect. Further refinements to this experience are planned for future updates.
Known Issues
As with any new build, there are a few known issues in build 26120.1930:
General
- Some users may encounter installation failures with error 0x800f0983. If this occurs, attempting the installation again is recommended, as it should succeed on retry. If the installation remains at 0%, patience is advised as it may eventually proceed.
Start Menu
- Clicking or tapping on a letter in the Start menu’s All apps list may cause the list to malfunction. If this issue arises, rebooting or restarting explorer.exe may resolve it.
