Steven mentions Niva Regrun in one of the previous posts. RegRun allows you to have "startup profiles" and it even allows you to invoke / chose which profile including "clean boot" during startup. It also has a whole slew of other security tools and it comes in a multitude of versions. It's extremely competent software but I would venture a guess that platinum could be almost overwhelming to some home users because of the extensive features and along with that I think that if it is misconfigured there is potential for it slowing the computer down.
I own Chameleon but the thing I did not like about and it has hopefully changed is that it didn't realize a new program has been added until restart of the OS. If this has changed please let me know because I wouldn't want to misinform anyone. Partial quote:
Hi, TrilineaSee complete response by author Evgeni further down in this thread.
In the new version monitoring is carried out in real time
A program that is actually very good and it focuses on just startup functionality and I think it lets you have profiles but I can't say for sure is absolute startup. It hasn't been updated for a while l but I think it probably still one of the best in this category.
Steven I am sorry if I have strayed off your original topic, I would say that Niva Regrun probably fits into your original description of a paid product that does what you talk about. I am not sure if you've tested it but I saw that you listed it.
