Announcing Windows 11 Insider Preview Build 26120.1252 (Dev Channel)

Hello Windows Insiders,

Today we are releasing Windows 11 Insider Preview Build 26120.1252 (KB5038603) to the Dev Channel. This update is delivered in a format that offers a preview of enhancements to servicing technology on Windows 11, version 24H2. To learn more, see https://aka.ms/CheckpointCumulativeUpdates.

REMINDER: Windows Insiders in the Dev Channel will now receive updates based on Windows 11, version 24H2 via an enablement package (Build 26120.xxxx). For Insiders in the Dev Channel who want to be the first to get features gradually rolled out to you, you can turn ON the toggle (shown in the image below) to get the latest updates as they are available via Settings > Windows Update. Over time, we will increase the rollouts of features to everyone with the toggle turned on. Should you keep this toggle off, new features will gradually be rolled out to your device over time once they are ready.

Going forward, we will document changes in Dev Channel builds in two buckets: new features, improvements, and fixes that are being gradually rolled out for Insiders who have turned on the toggle to get the latest updates as they are available and then new features, improvements, and fixes available to everyone in the Dev Channel.

Changes and Improvements gradually being rolled out to the Dev Channel with toggle on*
