Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 28020.1685 to the Canary Channel. (KB 5079381)

What’s new in Canary Build 28020.1685

Improved reliability of removing Windows Update files / windows.old files via Settings > System > Storage.

You can now use voice typing (Windows key plus H) when renaming files in File Explorer.

These builds can be unstable and may be released with limited documentation. Join Windows Insider – Get early access to Windows 11 features & updates

Many features in the Canary Channel are rolled out using Control Feature Rollout technology, starting with a subset of Insiders and ramping up over time as we monitor feedback to see how they land before pushing them out to everyone in this channel.
The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
Some features may show up in the Dev and Beta Channels first before showing up in the Canary Channel.
Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.
To get off the Canary Channel, a clean install of Windows 11 will be required. As a reminder – Insiders can’t switch to a channel that is receiving builds with lower build numbers without doing a clean installation of Windows 11 due to technical setup requirements.

Check out Flight Hub for a complete look at what build is in which Insider channel.

Thanks,
Windows Insider Program Team
