I went to change startup programs and it says windows Defender is turned off
Is Windows Defender supposed to be already turned on when you buy a new PC?
and what startup programs are safe to turn off ?

From MS:
"If you are using Windows Vista, you already have Windows Defender, although it might be turned off if you have Antivirus security software installed."

Windows Defender is now on in Vista for me, but I do not believe that was initially the case.
(I could be wrong)
But all that Defender is is an anti-Spyware program. So if you already have one installed (like most of us do), I see no real use for it. Although I do not believe it loads at start-up, it probably (like everything else in Vista) is a resource hog - and I am actually going to look into it.
As far as which start-up programs are safe to turn off... it depends upon what software you have on your system. Some require that they load when Windows loads. But I have personally found that very few truly need to (for example, QuickTime - most have it installed but it does not need to load at start-up and is safe to disable. While others - say ZoneAlarm or AVG - do need to load at start-up).
There are sites devoted to informing you about which programs are safe to disable for selective start-up. I will try to lead you to a few later today, but if someone else can provide assistance, I thank you in advance, as I do not have any to list at the moment.
