Error codes are numerical values that represent the outcome of a specific operation or event in a computer system. They are essential for troubleshooting and debugging purposes, as they provide valuable information about what went wrong and how to fix it. In the Windows environment, error codes play a crucial role in diagnosing issues and resolving them effectively.

Windows Error Codes are specific to the Windows operating system and are used to indicate the success or failure of various system functions. These codes are typically displayed in the form of a hexadecimal number, such as 0x80070005, and can be found in error messages, event logs, or returned by system APIs.

Understanding error codes is essential for Windows administrators, system engineers, and developers as it enables them to identify and resolve issues quickly. By deciphering the error code, one can gain insights into the root cause of the problem and take appropriate actions to fix it.
