PS I also own WinTasks Pro and like it a lot. Increasingly, though, I find myself using Taskman instead... WinTasks is powerful but not nearly as configureable as I would like. For example, I find the information that it will display (the columns that you can add to view) limited in terms of its configureability and one of the selling points for me when I bought it - the way it displays running processes paths, etc. now annoys me! I'd like just to be able to sort it and find the exe file name, PERIOD, not have to wade through all the path names or the complete name of the file, including the author's name (svchost.exe rather than Microsoft Service Host Process. Picky, picky, I know). For another, I can't find any means of displaying Virtual Memory usage. I should play around with it more as I can't believe that this isn't an option that's already present.
Haven't tried it as a startup manager. I purchased it as a Taskman replacement and already had WinPatrol for Startup management. Given that I've been following Scott's creed of late and trying to purge my system of bloat (I have multiple file managers, file viewers, archive managers, etc.) perhaps I should revisit this and see if one or the other of these apps is a candidate for removal... Hmmm. Food for thought.
Hope this helps (I have a wicked case of verbal diarrhea, yet have an appalling case of writer's - thinker's - block with my dissertation. Interesting...).
