It does have better security built in than Windows XP. Always make sure to have an anti virus software of your own though.
Windows Vista has numerous security improvements over XP, such as User Account Control (UAC).
Windows XP is better. Vista is a better at running games, but it is slower and more problematic than XP

"SP3", or service pack 3, is a cumlative set of security and bugfixes for Windows XP, both the Home and Professional editions.

There is no such thing as "Windows XP Vista." There is Windows XP and there is Windows Vista. They are two different versions of the Windows operating system (XP is older than Vista). As to which is better (XP or Vista) if that is your question -- I think most people would say that XP is better, but this probably depends on which operating system you are used to and what type of work you do with the computer. That said, even Windows Vista is out of date, now. New machines will have Windows 8 (or Windows 7 if it is slightly older).
I don't think so.
windows Xp is better but Vista is slightly faster
Windows Vista is the successor to Windows XP.
