thegline.com: "For those of you who missed it the first time around, the PowerToys and TweakUI are some of the most popular add-on downloads for Windows around. This new version is specifically for Windows XP and no other version of Windows -- not even Windows 2000 -- so XP users will want to give this an in-depth reading. Note that if you have any previous versions of these applications installed, you will need to uninstall them completely before you can load the new ones. Tweak UI itself is easily the most powerful and versatile of the apps listed here, so I'll tackle it first. The idea behind Tweak UI is just as the name would imply: it lets you edit or 'tweak' various undocumented features in the Windows user interface. There are tons of settings broken down into various categories; you could easily spend an hour or two wading through them all. I'm going to go through most of them briefly here and note what changes I made to my own system and why."
