Scenario

  • When you are clicking Windows button on your keyboard and nothing is happening.
  • If you are trying to open Start menu by clicking Win+X keys, no Start menu is appearing.



Why is it happening?

It may happen if ShellExperienceHost.exe, SearchUI.exe  stops responding or malfunctioning. These are associated with controlling of Start, Search or Taskbar. If they malfunction, then notifications, Microsoft Edge, Windows 10 apps including Settings, volume, WiFi, battery icons will also stop responding along with Start or Start menu.
