I've faced a common issue many times before which I'm sure you have seen as well.
Users complain that their "computer is too slow", and often, it's to do with the startup time of windows. I know that Windows would be it's slowest when starting up due to all the services and background processes and software starting up. I accept that this is normal.
But in some cases, the hard disk activity keeps going crazy for 10-15 minutes AFTER the user has logged on. I'd just like to know if there is any tool out there that can tell me what software is the culprit that causes this.
