Process Hacker

A free, powerful, multi-purpose tool that helps you monitor system resources, debug software and detect malware.

Graphs and statistics allow you quickly to track down resource hogs and runaway processes.

Use Ctrl+I to view system performance information. Move your cursor over a graph to get a tooltip with information about the data point under your cursor. You can double-click the graph to see information about the process at that data point, even if the process is no longer running.

Can’t edit or delete a file? Discover which processes are using that file.

Use Ctrl+F to search for a handle or DLL. If all else fails, you can right-click an entry and close the handle associated with the file. However, this should only be used as a last resort and can lead to data loss and corruption.

Get real-time information on disk access.

This may look very similar to the Disk Activity feature in Resource Monitor, but Process Hacker has a more features!
