Improving your search experience:

We’re rolling out a change to display some of your recent searches when you open Windows Search Box, to make them easy to get back to. This change is rolling out server-side to everyone on version 1903 and higher:

    • The recent list shows the last four items that you’ve searched for and opened from Windows Search Box, which can include apps, files, settings, and direct-nav URLs (for example, like “”).
    • You can remove individual items in this list by clicking the “x” that shows when you hover your mouse over the items.
    • You can disable the Recent feature by turning off the Windows setting “Search history on this device” under Settings > Search > Permissions and History.
    • If you’ve not used Windows Search Box before and have 0 recent items, the recent list will be hidden.
      If you don’t use Windows Search Box often and have fewer than 2 items in the recent list, an educational string will display in the area to let you know what types of items will appear in the list.
Showing Search, with Top Apps, Quick Searches, and now, newly a Recent section.

Improvements for Enterprise:

  • Windows Management Instrumentation (WMI) Group Policy Service (GPSVC) updating performance improvement to support remote work scenarios.
