That's right, you're not looking hard enough. there are currently TWO active topics that deal with reasons microsoft suck. One is in the lounge or somewhere, the other was just started a few days ago in the Unix/Linux forum by somebody too impatient to find the other one himself!
Well, go and look in Unix/Linux>Reasons Microsoft suck cock or something similar and i have put a link in there to the other thread too...
Re: startup, yes there are a few places, but i don't know where they are. One handy thing for checking ALL the programs that run on startup is System Mechanic from IOLO. It's payware but you get to use it for free for a month. It has a function where it displays all the startup programs in a list and you can disable or delete them if you like.
Careful though, if you delete something, System Mechanic won't put it back and you'll need to reinstall it. On the other hand, if you just disable it a lot of the shittier applications detect that their agents are disabled (all the realnetworks stuff for a start) and just add another shortcut to bypass your disablement! this can be remedied by deleting the entry completely.
Good luck. No links here because i am unwilling to fire up google and dogpile again when it'll be good practise for you to go and do it yrself.
Happy Hunting....
