Windows Vista only: Ultimate Windows Tweaker makes no bones about its source of inspiration—the uber-specific, XP-customising Microsoft tool TweakUI—and does pretty well by it. There's more than 130 changes to make from this stand-alone, no-install utility, including some seriously helpful User Account Control hacks and sliding timers for application killing, along with all the other tweaks for menus, Explorer, and shortcuts TweakUI users will find familiar. Another great feature: A big, prominent "Create System Restore Point" button to hit before you get to tweaking, which is always a good idea. Ultimate Windows Tweaker is a free download for Windows Vista systems (32- and 64-bit) only. Thanks, How-To Geek!
