Microsoft's latest Windows 11 Canary build introduces new features and lets users say goodbye to Cortana


Earlier in the week, Microsoft rolled out a new Insider build for testers in the Dev Channel. Today, arriving just in time for the weekend, it delivers a new flight for those on the Canary Channel.
Windows 11 Build 25921 brings some interesting new features including HDR background support and rich thumbnail previews for cloud files on Start. It also lets users uninstall Cortana.
Microsoft is launching a new Canary Channel for exceptionally experimental builds of Windows 11 (and Windows 12?) in a major Windows Insider Program overhaul


Microsoft has detailed some of what it has planned for Windows 11 over the coming year, including big changes to the Windows Insider Program. As well as "rebooting the Dev Channel from the ground up", the company is also launching a new Canary Channel where we could see the first signs of Windows 12.
The idea of Canary builds will be familiar to many web browser users who like to be on the cutting edge. The likes of Google Chrome and Microsoft Edge have Beta, Dev and Canary builds offering varying degrees of stability and experimentation. Now Microsoft is updating the Windows Insider Program so it will have four channels -- Release Preview, Beta (22000 series), Dev (23000 series), and Canary (25000 series).
