Which of the following keyboard shortcuts is used for opening the Run dialog box in the Windows operating system?

Explanation / व्याख्या:

In the Windows operating system, the shortcut Windows key + R is used to open the Run dialog box.

The Run dialog box allows users to quickly open programs, system tools, folders, and settings by typing commands.

For example:

• Typing cmd opens Command Prompt
• Typing control opens Control Panel
• Typing notepad opens Notepad
• Typing msconfig opens System Configuration

Why other options are incorrect:

• Windows key + Q → Opens Search (in some Windows versions).
• Windows key + W → Opens Widgets or Workspace (depending on version).
• Windows key + O → Locks screen orientation (mainly for tablets).

Only Windows + R directly opens the Run dialog box.
