Was looking through the recent thread about tweaking Firefox and there was a link to a Firefox tweak guide. Well that guide was from a page where there are many other tweak guides. On this site is two user guides, one for XP and the other for Vista. These are the best guides I have seen for Windows yet. They are in PDF format and they are between 2-3 MB in size and free for download. The XP one is over 170 pages long and covers every thing you can imagine. This is what should have come with Windows. Everybody, even advanced users, will learn something from these guides. These will be going on all my machines and family and friends machines. They are layed out in a very easy to use way and explain things in a way even beginners will be able to understand.
