Microsoft has released an optional Windows 10 update that it says fixes some lingering Search box bugs.
The update for Windows 10 versions 1903 and 1909 “updates an issue that prevents the Windows Search box from rendering properly”.
Earlier this month, Windows users complained that an update was preventing them using the built-in Windows Search feature, which was serving up a blank grey or black box. Though at the time Microsoft said a fix was rolled out that should address the bug after the system was rebooted.
