Incidentally, I advise against installing the latest XP service pack, SP3, due to widely reported problems. Additionally, SP3 offers little beyond the countless Windows Updates that have been released separately since SP2. If you regularly download and install these Windows Updates, there is no compelling reason for the average user to download and install the risky SP3.
Vista was obviously poorly received overall by home users and businesses alike, due to problems with reliability, security, compatibility, and responsiveness. Vista epitomizes the bloatedness and sluggishness that M$ is (in)famous for. A few examples of perplexing problems I have personally encountered with Vista:
- A Windows Update that essentially forced Vista to self-destruct. It would not even boot the recovery partition.
- I have never been able to convince Vista to properly work with a projector. I've never had a significant problem connecting to a projector from XP.
- Productivity hits via unintuitive settings placement and overall sluggishness.
- UAC. Enough said.
