Microsoft has released Windows 11 Insider Preview Build 27863 to Windows Insiders in the Canary Channel. The update includes support for the new post-quantum signature algorithm ML-DSA in the NCrypt and BCrypt cryptography APIs, along with the Crypt32 certificate APIs. The update addresses problems with Windows Sandbox, ensures core Windows surfaces load correctly in safe mode, and resolves issues with msftedit.dll that were causing application crashes for users utilizing Hebrew or Arabic display languages.
Announcing Windows 11 Insider Preview Build 27863 (Canary Channel)
Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27863 to the Canary Channel.
Changes and Improvements
[Post-Quantum Cryptography]
- As announced this week at the Build conference, we are adding support for post-quantum signature algorithm ML-DSA in NCrypt and BCrypt cryptography API surfaces, as well as Crypt32 certificate APIs. Three variants are supported, ML-DSA 44, 65, and 87. In Build 27858 and higher, we encourage you to try out using and validating ML-DSA certificates with these changes.
Fixes
[Windows Sandbox]
- Fixed an issue causing Windows Sandbox to not work and show error 0xc0370106 on launch in the previous flight.
[Other]
- Fixed an issue where core Windows surfaces were not able to load in safe mode (File Explorer, Start menu, and others) after the previous flight.
- Fixed an issue with msftedit.dll which was causing apps like Sticky Notes and Dxdiag to crash in certain cases for people using Hebrew or Arabic display languages.
