For those of you that remember and loved the TweakUI utility from Microsoft, Ultimate Windows Tweaker is a freeware tool that takes the concept of the old TweakUI and supercharges it for Windows Vista and 7. You can tweak hundreds of settings and variables—system tray icons, the menu pop-up speed, security settings for the control panel, and a lot of other things you can’t normally get to. It’s a 380 KB, stand-alone portable application.
For those of you who are not yet familiar with all the tools available in Windows 7 or you are the kind of person who has his desktop filled with useful shortcuts, we’ve created for you the biggest library of Windows 7 shortcuts. You’ve got almost everything you need and we are very willing to expand it. For starters, we’ve created 99 Windows 7 shortcuts which you can download and use. They are all created in such a way that they work on every Windows 7 computer. Also, if you want a shortcut which we don’t have in our collection, leave a comment and we will update it.
