Explorer.exe
Explorer.exe is the Windows Program Manager or Windows Explorer
The Windows Explorer debuted in Windows 95 as a replacement for the older Windows 3.x File Manager. It could be accessed by double-clicking the new My Computer desktop icon, or launched from the new Start Menu (which succeeded the earlier Program Manager).

While “Windows Explorer” is a term most commonly used to describe the file management aspect of the operating system, the Explorer process also houses the operating system’s search functionality and File Type associations (based on filename extensions), and is responsible for displaying the desktop icons, the Start Menu, the Taskbar, and the Control Panel. Collectively, these features are known as the Windows Shell.
