Ditto for "selective startup".
I use an HP Photosmart 3110 scanner/printer/fax, and it is totally undemanding - able to be configured within its own program settings not to take over at start, didn't have to use msconfig at all. I think some of the worst items of bloatware are Quicktime (as mentioned) and Adobe's PDF program. Got rid of those two real smart! If anyone still uses Real player, that's pretty bad, too. Oh, and then there's Norton....
But the OS itself has quite a few services set to automatic that the average user will never need or want.Rather bloaty. There's a very good guide/tutorial for choosing what to disable and how (and why)
here
(Ironically, disabling certain items also has the side affect of making Windows more secure from some vulnerabilities.)
