Which application or feature opens when you press Windows key + E in Microsoft Windows?

The Windows key + E keyboard shortcut opens Windows File Explorer, traditionally known as Windows Explorer in older versions of Microsoft Windows. File Explorer is the built-in file management tool used to browse, organize, and access files, folders, and storage devices on a computer.

With this shortcut, users can quickly open File Explorer without navigating through the Start menu or clicking its taskbar icon. From there, they can access locations such as This PC, Downloads, Documents, Desktop, USB drives, and network locations, depending on their system configuration.

The other options are associated with different functions. Utility Manager was an accessibility tool in older Windows versions and is associated with the Windows key + U shortcut in traditional MCQs. Show Desktop (toggle) is performed by Windows key + D, while the Run dialog box opens with Windows key + R.

Therefore, Option A — Windows Explorer is the correct answer. Remembering common Windows keyboard shortcuts can help users work more efficiently and is useful for computer fundamentals and operating systems examinations.
