What is the difference between a clean install and the upgrade and where
do i
choose?
High level overview:
Upgrade occurs from within the existing OS... insert the Vista DVD while
logged into XP desktop and kick off the Vista install. The upgrade attempts
to capture/migrate all your existing software into the Vista install.
A clean install occurs when you boot from the Vista DVD and install from
there. The clean install does not capture/migrate all your existing software
into the Vista install. You must reinstall all software after doing a clean
install. If you don't format the drive on which you're installing Vista, it
will move some Windows stuff into a directory named Windows.old from which
you -might- be able to get back to XP without reinstalling it if you follow
somewhat detailed work instructions available in a MS KB article. If you
format the drive during the clean install, you've cast all XP artifacts to
the wind and must start from scratch if you want to go back to XP. And, of
course, you'll have to back up all your data prior to doing the clean
install (not that you wouldn't with an upgrade, but... well, you know...)
I've only done clean installs with Vista, formatting the HD's during
install, and my Vista experience has been positive. Yes, IE has stopped
working a few times over the past couple of months, but by and large, things
have been good. Needless to say, I recommend clean installs of Vista.
Good luck,
