Programs like this only create an environment where 3 years down the line, people still dont know where to go to view a process list, check their battery level, or even know where to look for what programs are starting up.
That's OK. They can use TweakVista for all of those.

But watering down the simple stuff, and allowing users to change settings without educating them on what it's actually doing is not a good idea.
You should find there are quite a lot of tooltips scattered around the program, most notably on the more informative areas of the Power, Assessment and Services tabs. Ultimately, though, it's
not our job to educate users, as much as they might be better computer users if they did spend time learning the whys and hows. It's to help them solve their problems without
having to be "educated". That's what they're paying for - they're trading money against time.
Learning how to use Windows better is not good enough, because Windows Vista itself is sorely lacking in many areas. For example, have you tried clicking "Change startup programs" in Control Panel? It doesn't actually let you do it! This is where you or I would mutter "Vista!" and learn about regedit. However, it is where the target users of TweakVista would give up. And that is why the program is useful for them - because they can easily see "hey, here's the things that are running on startup, perhaps if I untick them things will improve". Often they're just trying to get rid of an annoying piece of software that came with some old hardware and does nothing useful for them but break occasionally.
Where Control Panel offers the functionality the user is likely to be looking for, or more advanced functionality that it would be useless to duplicate, we tend to link to it. We cannot replace everything, and we're not trying to. We
are trying to hit a few specific targets where we think there is a need for it.
