We have covered few tweak utilities here, I’ve also mentioned a small teak utility called “Windows 7 little Tweaker 1.1″ that designated for Windows 7 to save your time and speed up your machine. However, with the little Tweaker it only works for 32 bit machine, people have requested 64 bit and it won’t work. Thanks to theWindowsClub we now have an “ Ultimate Windows Tweaker ” with a much richer UI and function that works for both Windows 7 32bit and 64bit .
