Cannot Start Network Services

I am helping a friend who has a slow running windows 7 (32bit), quad 4 PC. I did a lot of tweaks to the machine - mostly aesthetic - but now I can't get her computer to to access the internet and the system restore is FUBAR.Here is what I did, in order:

~First I created a new system restore point.

~Then I found that she had Mcafee, Avira and windows defender installed, so I uninstalled McAfee and windows defender and rebooted - no problems. (I read that having more than one anti-virus can cause a slow PC)

~I ran super super antispyware and it found only a few tracking cookies but that was it.

~I then turned off aero themes and aero peek and snap.

~ I set her power settings to high performance because she likes to have a bunch of programs and windows open at a the same time.

~ I then went in to services.msc and disabled active x (she uses chrome), bitlocker, encrypt file systems, IP helper, microsoft iSCCI Initiator service, parental controls, remote desktop and configuration, smart card, media player network services.

~ I then went into msconfig and disabled a bunch of startup programs (itunes, quickplayer and the like)

I rebooted and everything was fine -- I went online and checked and things were great and the system was noticably faster. I then re-booted and there was no internet access and the network connection icon was missing. I checked and in msconfig, under services, and almost all of the microsoft services were unchecked. I tried re-checking the network information and some others I found via google, but after reboot they were still "stopped" - even though they were set to "automatic". I went into services.msc and tried to manually start them but got messages like "error 1068"Do I need to right click "run as administrator" when I select system.msc to make these start or since I was able to access service.msc without first selecting run as admin, do I already have administrator privileges?
