Nice guide Jack. A couple of things. First, I've read that keeping the page file constant in size (setting the min and max to the same size) helps performance. Not sure if this works, but it makes sense intuitively, as the machine doesn't have to adjust an already slow process on the fly. Second, in addition to defragging, I keep the page file defragged with a utility called (strangely enough) Page Defrag. Even after a standard Windows defrag, the page file can remain fragmented. I have heard that "Show windows contents when dragging" is one of the biggest video resource hogs. Also, browsing is sped up considerably if you don't load obnoxious banner ads. Mozilla's ad block extension helps with this, as does installing a hosts file (note that the latter will cause problems with referral site redirects, such as dealnews.com and techbargains.com). Of course, I use a full compliment of anti-spyware stuff, Ad-Aware, Spybot S&D, MS's program, Ewido, and Spyware Blaster. Also, Zonealarm and AVG free edition.
