This is a clean install of Windows 10 Pro x64.
Search box on the taskbar does not work. Clicking on the Search box makes it change color, but it is not possible to type anything into the box.
Opening Start Menu before clicking on the Search box sometimes helps. In 1 case out of 10 Search box suddenly starts working. But it only happens when Start Menu is open. When Start Menu is closed, Search box is unresponsive.
Trying to click on the Search box in such cases generates a barrage of entries in Event Viewer:
- In Application log, lots of errors like this
