It's your computer, so the choice is, ultimately, yours. (Although
it would have been a lot simpler to have just purchased the computer
with WinXP installed, to start with.)
However, there could be a couple possible adverse repercussions of
which you should be aware. First and foremost, if the specific computer
model in question was designed specifically for Vista, there may well be
no WinXP-specific device drivers available to make the computer's
diverse components work properly. Consult the computer's manufacturer
about the availability of device drivers. Secondly, removing an
OEM-installed operating system and replacing it with another will almost
invariably void any and all support agreements and, sometimes, even the
warranty. You would, at the very least, have to re-install Vista before
getting any support from the manufacturer. Again, consult the
computer's manufacturer for specifics. Thirdly, there may be the
additional cost involved in purchasing a WinXP license for this new
After backing up any data you wish to transfer to the new OS
installation, simply boot from the WinXP installation CD. You'll be
offered the opportunity to delete, create, and format partitions as part
of the installation process. (You may need to re-arrange the order of
boot devices in the PC's BIOS to boot from the CD.)
HOW TO Install Windows XP
Then, assuming you were successful in obtaining WinXP-specific
device drivers so that the computer can be made to work with WinXP, the
backed up data can be restored and applications (those that are
WinXP-compatible, that is) re-installed.
