The difference between windows XP and Vista are: The Box colors, instead of being solid colors, they're translucent. The Text on the boxes differ as well. You can also download widgets on the Vista. However, the XP is faster.
vista is also trying to look/work like an i-mac with many small extras compared to xp although does not really work as is sort of half way between an imac and an xp
No. Due to the length of time between the releases of Windows XP and Windows Vista, as well as Windows Vista ditching support for some legacy technologies, there are many devices that will not function in Windows Vista but work in Windows XP.
No. Obviously, if you upgrade to Windows Vista, you will have Windows Vista.
XP, if you can scratch Vista and go for Windows 7
windows Xp is better but Vista is slightly faster
Drivers written for Windows Vista are not backwards-compatible with Windows XP. Most hardware that has a driver for Vista should also have a driver for Windows XP.
They are "compatible" in the sense that many applications that run on Windows XP will run on Windows Vista.
Yes. There is a process called Dual Booting, but it requires two hard drives. Just search for "how to dual boot windows vista and windows XP?".
Yes ofcourse, Windows Vista is upgraded version of Windows XP. Obviously it can run Windows XP applications.
"Vista XP" is not a computer type. Vista and XP are both previous versions of the Windows operating system. The current version of Windows is Windows 8.1.
Windows XP is better. Vista is a better at running games, but it is slower and more problematic than XP
Windows Vista is notably far more secure than Windows XP.
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 That said, even Windows Vista is out of date, now.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).
