<XP multiple log-ons & start-up utilities>

[Juud]

I have dutifully done a search for earlier topics, and have found related threads that only confused me more (no need to go into whose fault that is )

1.
As per advice on this forum, on the family desk-top PC, XP is set up with an Admin log-on with all powers, and 4 separate limited power log-ons for each family member.
Does an operation (Norton update, AdAware scan) performed in Admin log-on mode work for the whole computer?
And does the same operation when logged on as a user only work in that users 'space'?

2.
Start up for each user is painfully slow. When I type MSCONFIG into 'run' I get a list of 13 different names. I recognise 3 or 4 of these, so no idea what I can and cannot disable to speed things up. Have had a look at the BlackViper website, and when I do things as per him and type 'services.msc' into the run box, I get a list of about 50 incomprehensible items.
Any simple ideas about how I would know which start up utilities I could safely 'stop from starting' ?


Grateful for any and all enlightenment
