Which file starts MS Word?
Answer:
winword.exe
The correct answer is **A) winword.exe**. When you launch Microsoft Word on a Windows operating system, the executable file that is initiated is named `winword.exe`. This file contains the core program code for Microsoft Word, and running it is what loads the application, its interface, and its functionalities. While other options might seem plausible, `winword.exe` is the specific system name for the Word executable. `word.exe` and `msword.exe` are not the standard executable names for Microsoft Word. `word2003.exe` is too specific to a particular version and even then, it's not the conventionally recognized executable name; newer versions of Word would have their own specific executable names, but the underlying convention points to `winword.exe` as the primary starter.
