Insider KB5070899 Windows 11 Insider Canary build 27975.984 - Oct. 27

UPDATE 11/04:



UPDATE 10/27/25: We are starting to roll out Cumulative Update Build 27975.984 (KB5070899). This update does not include anything new and is designed to test our servicing pipeline for builds in the Canary Channel.

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27975 to the Canary Channel.

What’s new in Build 27975​

[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.

Fixes​

[Input]​

• Fixed an issue impacting touch keyboard launch reliability in the latest Canary builds.

[Windows Hello]​

• Fixed an issue impacting certain devices which was causing the Windows Hello PIN to not work after upgrading to the latest Canary builds, until you set it up again.

[Settings]​

• Fixed an issue causing Settings to crash when accessing drive information under Settings > System > Storage. This also impacted accessing the drive information from the properties when you right clicked a drive in File Explorer.

Known issues​

[Start menu]​

• Insiders with the new Start menu may experience it unexpectedly scrolling to the top.

[Power and Battery]​

• We’re investigating reports that sleep and shutdown aren’t working correctly for some Insiders after the latest Canary builds.

Reminders for Windows Insiders in the Canary Channel​

• The builds we release to the Canary Channel represent the latest platform changes early in the development cycle and should not be seen as matched to any specific release of Windows and features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they’re ready.
• 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.
• 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.
• The desktop watermark shown at the lower right corner of the desktop is normal for these pre-release builds.
• Check out Flight Hub for a complete look at what build is in which Insider channel.

Thanks,
Amanda
