26200.5562(KB5055642) for Windows Insiders in the Dev channel.

Full build number: 10.0.26200.5562.ge_prerelease_im.250415-0947.

Reminder: The Dev channel has moved to builds numbered 26200. This means the option to switch from Dev to Beta channel will close after installing build 26200.5510. If you haven't switched to Beta yet but want to, you can pause updates when build 26200.5510 appears in Windows Update, switch channels, then resume updates.

Builds numbered 26200 are based on Windows 11 version 24H2 and will include many features and improvements available in 26120 builds for the Beta channel. Over time, developers will begin making platform changes that may cause known issues to differ from Beta channel builds.
