With Windows 11 now very much Microsoft’s focus, it might come as something of a surprise to find that the company is still adding things to Windows 10 — but with the release of the KB5011543 update, this is precisely what is happening.

This is a preview of the update that will be officially released on April’s Patch Tuesday, and it is designed for Windows 10 20H2, Windows 10 21H1 and Windows 10 21H2. What can you expect in this update? In addition to the arrival of search highlights — with slightly different looks for enterprise users and ordinary consumers — there are numerous bug fixes, and changes to the Action Center.

The KB5011543 update was previously made available to Windows Insiders only, but now it can be installed by any Windows 10 user who is interested. Bug fixes include addressing problems with Outlook search, issues with TPM, and various Bluetooth-related error messages. But it is the new features that are of most interest. The Search Highlights feature has been ported from Windows 11, and there is a new policy that changes the way some notifications work in the Action Center.

Microsoft says of the new functionality:

Search highlights will present notable and interesting moments of what’s special about each day — like holidays, anniversaries, and other educational moments in time both globally and in your region. To see more details at a glance, hover, click, or tap on the illustration in the search box.

For enterprise customers, search highlights will feature the latest updates from your organization and suggest people, files, and more. 

Search highlights will roll out to Windows 10 customers over the next several weeks. We are taking a phased and measured approach. Broad availability will occur in the coming months.
