Some of my posts have prerequisites. I walk home thinking I should definitely blog about that cool (honestly) troubleshooting session and realize that some previous posts to describe tool needed are missing.
Process Explorer is tool so powerful and so important that it was hindering a lot of posts.
What it does
Basically Process Explorer is what Windows Task Manager should be. It shows software processes running in the system but :
- in better color-coded way;
- more customizable interface;
- with precise history of recent system load.
Processes are presented in tree view by default. That makes easier to understand order in which they were launched and turns executable-intensive tasks like installing software in quite a show.
Clicking performance graphs shows separate window with bigger version of those and plenty of performance-related information.
Default view may not seem like much but there are a lot of additional columns available. Depending on task at hand Process Explorer can be used to show anything from developer information embedded in executable to per-process CPU graphs.
Double-clicking any process gives one more window with application-specific load graphs, network connections and plenty of other info.
Excellent (as usual) freeware utility from Sysinternals . Writes some settings to registry so not completely portable but works without installation . Can be easily set to replace Windows Task Manager in options.
Closer to techie toy and resource hungry… But it’s best in it’s class.
