Hi,

A while back this article was posted online. it is quite interesting and has a number of suggestions to increase speed on Vista.

The intro page is just a small paragraph, but click the link at end of paragraph to see rest of article.

Windows-7 allegedely is running faster than Vista, so perhaps Microsoft have found a few tweaks also; might be worth keeping an eye out on their Vista Forums.
