What is WhatIsHang?

WhatIsHang is a lightweight system diagnostics utility for Windows that helps troubleshoot system hangs, freezes and performance degradation issues. It works by monitoring and logging critical system information in real-time, including CPU usage, memory usage, disk activity, running processes, active services, system events, registry changes etc.

When the system hangs or suffers from lag, WhatIsHang logs snapshot the system state during that time. These logs can then be analyzed to identify the offending process, service, driver or other factor responsible for the problem. Advanced filtering makes it easy to pinpoint the culprit.

Unlike other diagnostics tools, WhatIsHang has near zero overhead and can run persistently in the background without slowing down the system. Its small footprint also means it can run easily on old systems.

WhatIsHang is useful for both IT professionals and regular users to troubleshoot various problems like:

• System crashes, lockups and blue screens
• Applications hanging or not responding
• Abnormally high CPU or memory usage
• Slow system performance

The detailed logs and insights into system state makes it easier to identify and fix the root cause instead of just the symptoms. WhatIsHang saves time and frustration when dealing with system issues.
