The Ultimate Windows Tweaker has been updated with 20 additional tweaks for Vista (150 in all). Even better news is that it appears to work with Windows 7 as well.
According to DownloadSquad, the new 1.1 software worked well on the beta 7 install, save for a single error message that didn't seem to have any effect on the changes. Overall, the tweaker allows users to customise their UI and performance with a single click—it can even fit on a flash drive for portability. Plus, its free—so you have nothing to lose.
