In windows, after selecting my-computer or this-PC icon on desktop, system properties can be viewed by pressing shortcut key............

Question

Accepted Answer

The correct option is 2:

In Microsoft Windows, the keyboard shortcut **Alt + Enter** is the canonical and most efficient way to access the properties dialog box for almost any selected item. When you select an icon on your desktop, such as 'My Computer' or 'This PC', and press Alt + Enter, the operating system instantly opens a comprehensive window displaying detailed information about that item. For the 'This PC' icon, this command is an immediate shortcut to the System Properties window, which contains critical configuration data about your computer's hardware, Windows edition, and device specifications, bypassing the need to right-click and find the 'Properties' option manually from the context menu. This is a fundamental shortcut that all Windows users should know for quick system access.

The incorrect option is 1:
The **Shift + Enter** key combination is not used to view the properties of a selected item in Windows Explorer or on the desktop. In general application usage, the Shift key modifies the action of the key pressed next to it. For example, in a browser, Shift + Click on a link might open it in a new window, not a new tab. In file explorers, pressing Shift while performing an action can sometimes be used to perform administrative tasks or to open the containing folder of a shortcut, but it is universally understood to be unrelated to opening the standard properties dialog.

The incorrect option is 3:
The **Ctrl + Space** shortcut is primarily associated with selection actions or text input utilities. In a file explorer environment, it is often used to toggle the selection state of files or folders when selecting multiple items that are not in a contiguous block. In word processing or coding environments, it is commonly used for purposes like invoking auto-complete, code suggestions, or inserting a non-breaking space. This combination has no dedicated function for displaying the System Properties window, making it an incorrect choice for the question posed.

The incorrect option is 4:
The **Alt + Space** combination has a specific, consistent function in Windows, which is to open the System Menu (also called the Control Menu) for the currently active window. This menu appears in the upper-left corner of the window frame and provides options to manipulate the window state, such as Restore, Move, Size, Minimize, Maximize, and Close. While it is a valuable shortcut for window control, it operates on the *window itself*, not on a selected desktop icon, and therefore cannot be used to open the system properties.
