Process Monitor
At a Glance
Process Monitor shows you an enormous amount of detail about each of those events, including its path, the operation it's performing, the process name, and details about it. You can also view similar information for Registry keys and current network activity. If you're not a developer or troubleshooter, you most likely won't find any use for this program. But those who program or need to track down problems will find it offers what they need, and most likely more as well.
