I hate Windows Vista

We bought a new home computer in September. I wish we'd bought one a few months earlier, before they all came installed with Windows Vista. I have taken all the steps I can find recommended on the Internet to speed it up, but it still has the habit of switching itself off - particularly in the middle of using Microsoft Word. Ihate the new MS Word interfaces too, and having to remember to save the document in an earlier version so I can read it on other computers.

Any ideas, you bloggers out there?
