windows Xp is better but Vista is slightly faster
I think yes because its more faster than Windows Vista.
No. Obviously, if you upgrade to Windows Vista, you will have Windows Vista.
Vista has DX 10 when WIndows XP doesnt. While Vista was suppose to be the upgrade to XP, it had a lot of problems during the first launch and it took awhile to fix everything. Vista is suppose to run faster, and use less resources on your system. But Vista failed and Microsoft then released Windows 7 as the replacement to Vista.
If you previously had windows vista, then possibly, yes. If you had windows XP then I doubt it.
People have had varied experiences with Windows Vista. Some have found it to be more efficient than XP; others have found it to be slower than XP.
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 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.
No.
