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.
Yes. The software needs to be able to use the commands and files that are available in Windows XP. Windows Vista will have these available as well as other files and commands that have been developed since Windows XP was released. However, do not confuse this with device drivers. If you have a piece of hardware that specifies that the drivers are for Windows XP, these will not necessarily work under Windows Vista and you will need to download the correct drivers from the manufacturer's website.
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.
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.
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.
There are no Vista drivers on the Canon website. You may be able to use the XP drivers but there is no guarantee.
Yes
After installing you need to delete vista os by deleting drivers and install xp ones again .
Videos made in Windows Vista will not work in Windows XP because the formats used to create the newer version of a WMM project are not available on the older version of XP.
Yes, it should.
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 That said, even Windows Vista is out of date, now.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).
No. Windows 95 supported only VxD drivers, which no Windows in the NT line (NT 3.1, 3.5, 3.51, 4, 2000, XP, Vista) support. Windows 98 supported both WDM and VxD. WDMs are the only supported driver model in 2000 and XP. If written well, a WDM driver from Windows 98 could work on Vista, but it is highly unlikely that hardware that runs with Windows 98 would be used in a Vista computer anyway. Also, certain components, such as the print spooler, have been totally rewritten for Vista, and thus the drivers do not work anymore. Vista-specific drivers also provide better performance.
No. Obviously, if you upgrade to Windows Vista, you will have Windows Vista.
