Which Windows component stores information for which hardware exists on the system, used in ongoing operation?

• A. Windows Registry
• B. Event Logs
• C. Power Settings
• D. Device Drivers

Answer: (A)

The Windows Registry stores configuration data and system state, including what hardware is installed and how it should be configured. This information is used during ongoing operation to know which devices exist, how they’re identified, and which drivers or services should load for them. For example, keys under SYSTEM\CurrentControlSet\Enum describe each detected hardware device and its properties, guiding how Windows manages those devices. Event Logs capture events after they occur, not the live hardware inventory; Power Settings control energy behavior, not hardware enumeration; Device Drivers enable hardware to function but don’t maintain the complete hardware inventory.
