Sometime you wonder why the machine is running slow after installing a bunch of programs even if you choose not to run them through Administrator Tools/Services.
Look at the following location in the registry and remove you don't need. I believe when you run "msconfig", it gives the same options. This is strictly related to Vista 64 bit and not 32 bit.
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run
Hope this helps!
