There's no such thing as an "XP memory card." Memory cards are operating system-independent.
if you have XP,yes.But you also need Vista for it to work.
Windows Vista DVD.
No. Vista Inspirat is a Vista theme for Windows XP. As XP themes do not work on Windows 7, the theme cannot be used as is.
Some Games will work on Vista even though it says ME/2000/XP some games that don't work with Vista Yet but if you try using XP Compatibility mode they might be tricked into thinking that Vista Is XP but some games are smarter than that.
Yes, it does but you won't be able to get everything out of it. Cards that are built for vista support DirectX10 while XP supports only up to (and including) DirectX9. The consequence is that your card won't be able to produce all the graphical effects (especially when gaming) that it could if it was used with Vista.
No. Generally not.
yes if you have anough vidio card, memory or RAM
Yes. It will work but only small games. Not all the games will work on Vista.
Games that are written specifically for Windows Vista will not work on Windows XP. Most games are written so that they will work on both.
This is kind of a two-part answer, because I'm not sure about the question. 1 - Halo (the original) will work on XP, and should work on Vista. 2 - Halo 2 will only work on Vista.
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.
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.
