2.1 What is Command Prompt?

Command Prompt is part of the Windows operating system. It provides a command-line interface for users to interact with the system. Through CMD, you can execute commands that perform various functions, from navigating files to changing system settings.

2.2 Benefits of Using Command Prompt

- **Speed**: Performing tasks via CMD can often be quicker than navigating through GUI options. - **Automation**: Users can automate tasks with batch scripts. - **Advanced Control**: Gain deeper control over system settings and configurations.

3. Why Change Date and Time?

There are several reasons why you might need to change the date and time on your computer: - **Incorrect Time Settings**: Time discrepancies can lead to issues with scheduled tasks, file timestamps, and software functioning. - **Time Zone Adjustments**: Moving to a different time zone requires updating the time settings. - **Testing and Development**: Developers might need to simulate different time scenarios for testing purposes.

4. Step-by-Step Guide to Change Date and Time
