I have a plethora of programs at startup and would like to stop some of them from turning on when my computer comes on. However, a large number of these programs I am unfamiliar with and/or have no idea whether they should be auto turned-on. Here's the list. Can anyone help me pick out programs that need to begin at startup? (I know it's alot I'm sorry, but I appreciate any help!)

1) Windows Defender (I already have AVG Free, is it unnecessary to run this addition window program?)
2) NVIDIA Compatible Windows Vista Display driver, Version 1
3) NVIDIA Media Center Library
4) HD Audio Control Panel
5) Realtek Voice Manager
6) RAID Event Monitor
7) Protector Suite QL
8) Google update
9) NVIDIA nTune
10) BisonHK
11) cyberlink brs
12) PowerDVD
13) Language Application
14) GrooveMonitor Utility
15) Adobe Acrobat
16) Java(TM) Platform SE 6 U5
17) HpqSRmon Security
18) hpwuSchd Application

I numbered them so they will be easier to reference in replies. Thanks in advance!!
