XP Visual Tools

http://www.jakeludington.com/downloads/xpvisualtools/

Tweak the Windows XP interface on the cheap. Add a custom WinXP logon screen from a wide selection of options. Quickly add custom themes to all apps on the system. Create custom wallpapers and rotate them on a set schedule, ranging from every 5 minutes to every 10 hours, or change wallpapers each time you logon to the system. Apply XP visual styles to non-XP apps, giving a fresh face to old favorites. Add transparency to the Start Menu or the taskbar, making it easy to still see what's on the desktop. The trial version includes only one style pack, but registration provides access to the full list of Visual XP Styles, in addition to a free Bonus Style pack, with seasonal updates of styles often provided free to registered users.
