Yes, you can but you have to check the hardware part of your computer. Also you need the upgrade version to keep your files and programs, otherwise you have to format.
Yes. You can dual boot both operating systems at once. Or you can install Windows XP over Windows Vista
As long as the computer meets the system requirements for Windows Vista, yes.
You should buy an upgrade version of Windows Vista however your computer if running XP is likely not to be powerful enough to run windows vista. You should run Microsoft Windows Vista Upgrade Advisor before upgrading as this will show you any problems your computer may have running Vista.
You can not simply downgrade to Windows XP from Windows Vista. If you want to completely remove Windows Vista in favor of XP, you will have to format the hard drive and reinstall the OS from scratch. Windows XP will not install on top of an existing Vista installation.
"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.
Microsoft Office can be installed on both Windows Vista and Windows XP operating systems. Microsoft Office 2013 will not install on Windows XP.
The easiest way is to format the system partition and install Windows Xp and then Vista. If you install Xp after Vista you might have to edit BOOT.INI manually. I beleave Vista will not allow you installing Xp when it's runnning. So you need a bootable XP (and Vista Home) CD/DVD. ------------------------------------------------------------------------------------------------------------ Actually it is possible to run both Windows XP and Windows Vista on the same computer but you will have to set up a Dual Boot setting up 2 partitions, formatting them to NTFS format, then installing XP on the first partition then Vista on the second.

You DO NOT have to wipe your hard drive or "downgrade" to run windows XP on a vista computer. Download and install Microsoft Virtual PC. its free and will allow you to run another operating system in a window of the current one you are running. You can have both!
XP themes are incompatible with Windows Vista. dno
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.
Sounds like a problem with Windows XP. What you should have tried to do is take the original hard drive, put in the xp install disk, to the install, choose to format the hard drive, and then continue with the XP install. BTW: XP > Vista. Linux > XP. You should install Linux, instead of XP.
Yea just format the harddrive and xp will take over and remove vista
New computers are not being sold with either operating system. If you want to use Windows XP on a new computer, you will have to purchase and install it yourself.
