I have Autoruns, but I think free WinPatrol is the most user-friendly startup control going: http://www.winpatrol.com/
Scotty will not offer to turn off anything necessary, and a 'disable' in the startup section does not remove it from the list. You can easily go back and 'enable' at any time. WinPatrol has many other benefits as well.
For what I have learned about controlling my processes, written in 'non-geek,' and including web addresses of useful tools and informational sites, see my Vox: http://doc1101.vox.com/
The 'links' are not 'live,' so copy and paste the URLs to your browser address bar, and "Go." No spyware, no ads, nothing to buy(or donate), just info.
