Today Microsoft is releasing Windows 11 Insider Preview Build 26100 to Insiders in the Canary and Dev Channels. Details as follows:

The Canary and Dev Channels receiving the same builds is only temporary. During the times in which the Canary and Dev Channels are on the same builds (e.g. Build 26100), the window is open for Insiders in the Canary Channel to switch to the Dev Channel. In the near future, the Canary Channel will jump to higher build numbers and the window will be closed so make your choice on which channel to be in soon!

NOTE: Some features may begin rolling out to the Canary Channel first before the Dev Channel even if the two channels have the same build.

Changes and Improvements in Build 26100

[General]

  • [REMINDER] The build watermark at the lower right-hand corner of the desktop is not present in this build and will return in future Insider Preview builds. This is part of our normal process preparing Windows 11, version 24H2 for releasing to customers later this year – but does not mean we’re done. Windows 11, version 24H2, will be this year’s annual feature update. As mentioned here, Windows 11 will have an annual feature update cadence that releases in the second half of the calendar year.

Fixes for known issues

[General]

  • Made another fix to address the issue causing shutdown and hibernate to not work in the latest builds.
  • Fixed an issue resulting in some Insiders seeing error 0x80240067 when trying to download app updates from Microsoft Store or Windows updates in Settings in the latest builds.

[Copilot in Windows]

[Windowing]

  • Fixed a DWM crash impacting some Insiders in the latest flights (this could result in you seeing your screen flash black).

Known issues

[General]

  • [IMPORTANT NOTE] We are investigating reports that some Windows Insiders in the Canary and Dev Channels are stuck on Build 26040 or Build 23620. The investigation is ongoing, however if you are impacted by this and really want to get onto the latest build in the Canary or Dev Channel today – you can download the latest ISO here and do a clean install and opt your device back into flighting in the Canary or Dev Channels.

[Copilot in Windows]

  • Voice access does not work reliably with the updated Copilot in Windows experience that introduces the ability for Copilot to act like a normal application.
  • Using Windows Ink to write in Copilot will not work with the updated Copilot in Windows experience that introduces the ability for Copilot to act like a normal application window.
  • When Copilot in Windows is docked and resized to a large width, Copilot does not always fill the width of the panel. Resizing Copilot usually fixes this issue.
