The Sysinternals team has updated its Process Monitor utility, an advanced monitoring tool for Windows that shows real-time file system, registry and process/thread activity. The Process Monitor 1.30 update adds support for importing and exporting filters, records system information in log files, presents more information about specific operations, includes translation of additional operation error codes, and tracks CPU and memory activity that it displays in a revamped process summary. Also check out Mark Russinovich’s Blog: The Case of the System Process CPU Spikes, where he shows how he used Process Monitor to track down a device driver causing CPU spikes.
