OT: info on processes in WinXP
Off-topic, but relevant to understanding more about the system that is running your Sonar software...
Most of us are already familiar with the Windows Task Manager. It's useful for seeing what processes are running and diagnosing potential conflicts when using your system as a DAW -- but it falls short in many ways, such as the location of the programs for those processes and any background information on those processes, etc.
There are a couple of useful tools in this regards and, rather surprisingly, one of them is part of Microsoft's free download "AntiSpyware (beta)". The other is a third party utility called WinTasks.
WinTasks shows the most complete information about the processes and it makes you wonder why Microsoft doesn't offer this information within its built in Windows Task Manager. However, there is some hope if their AntiSpyware utility is anything to go by. Not only does it seem like a pretty decent utility for the advertised task, it also has an option to view more detailed information about the processes that are running on your system. Not as comprehensive as the other WinTasks but a step in the right direction.
Anyway, I thought some of you might find this interesting. I know there are a bunch of utilities out there, plus more "hidden stuff" within Windows, so feel free to add anything in this area...
