Identify the event severity level in Windows logs for the events that are not necessarily significant, but may indicate a possible future problem.

In Windows Event Logging, the "Warning" severity level is used for events that are not immediately critical but may signify a potential future problem. These events highlight non-critical issues that, if left unaddressed, could lead to errors or system failures. An example is low disk space, which doesn't stop the system from functioning now but will cause problems if it runs out completely. This level allows administrators to take proactive measures before a significant issue occurs.

A. Failure Audit: This is a category within the Security log that records failed security-related events (e.g., a failed logon attempt), not a general system-wide severity level.
C. Error: This level indicates a significant problem, such as a service failing to start or a loss of data, which is more severe than a potential future issue.
D. Information: This level indicates the successful operation of a program, driver, or service. It is used for routine, non-problematic events.
