KB5079483


Microsoft has released cumulative update KB5079483 for Windows 11 version 25H2 for insiders on the Dev Channel – Windows 11 Insider Preview Quality Update (26300.8085).

The Dev Channel is transitioning to builds from the 26300 series, which means: after installing Windows 11 Insider Preview Build 26300.7674 and above, the window for switching from the Dev Channel to the Beta Channel will be closed. However, if a Windows Insider participant is currently on the Dev Channel and still wants to switch to the Beta Channel at the last moment, when the Build 26300.xxxx update appears in Windows Update, you can temporarily pause updates, change the channel to Beta, and then resume receiving updates.

Builds from the 26300 series will include many of the same features and improvements as builds from the 26220 series, which will continue to be released on the Beta Channel. However, over time, these builds will receive internal platform changes that may cause the list of known issues to differ between Dev and Beta.

Known issues in this build are not listed in the provided text. Microsoft invites you to send feedback about the pointer indicator and the updated Feedback Hub through Feedback Hub (Win + F) in the appropriate sections.

To install via Windows Update, go to Settings > Windows Update and click Check for updates. A computer restart is required to complete the installation.
