What is StartMenuExperienceHost.exe?

The friendly name is Start and it manages the Windows 10 start menu. It’s a new feature starting with Windows 10 version 1903. Before that, the start menu was handled by the Windows Shell Experience Host (Shell ExperienceHost.exe). That could lead to instability, for example, if the start menu experience issues, the whole exporer.exe could crash and need a restart. To improve the performance of the start menu, StartMenuExperienceHost.exe was introduced. If the start menu encounters problems, only the process StartMenuExperienceHost.exe requires a restart, not the whole system or explorer.exe.

The file StartMenuExperienceHost.exe on Windows 10 (1903-2004 version) is of size 762KB, and located in the C:\Windows\SystemApps\Microsoft.Windows.StartMenuExperienceHost_cw5n1h2txyewy folder. Microsoft has signed the file.
