The short version: a repair install is the minimum. Some would recommend a
clean XP installation.
In my opinion, the clean install isn't a bad idea, but it's a lot more work
than a repair install.
If you decide to go for the clean install, the "files and settings transfer
wizard" can make it somewhat less painful, but you'd still have to
re-install every application.
On the other hand, the repair installation will preserve most installed
applications and settings. Everything installed through Windows Update would
be lost, though.
