Windows 10 Build 19044.1620 (KB5011543) Preview and Download

Windows 10 is getting its optional update and as usual, it is available for versions 20H2, 21H1 and 21H2. The update is KB5011543, which raises the build number to 19042.1620, 19043.1620, or 19044.1620, depending on whether you're using Windows 10 version 20H2, 21H1, or 21H2. This update actually comes with a new feature called Search Highlights, which has been previously announced for Insiders. It's another improvement to the search experience.

New feature: Search Highlights

Search Highlights will showcase particularly interesting moments of the day, such as holidays, anniversaries and other real-time educational moments across the board and in the region. To see more details at a glance, hover, click or tap the illustration in the search box.

For enterprise customers, the search highlights will include the latest updates from the organization with recommendations for people, documents and more.

Search Highlights will be rolled out to Windows 10 customers in the next few weeks. We are using a phased measurement approach. It will be widely available in the next few months. For more information, see Group Configuration: Search Windows.
