This is a cool tweak for Vista where you can add “My Computer” to the task bar, makes access to your folders, media, documents, and programs real quick through the task bar. Since I have made this tweak it has made my access to my files that much quicker, and its a simple tweak.

This is a useful tweak but requires you to get down and dirty in the registry. If your screen setting is set to a high resolution then the screens on Alt+TAB looks a bit small and this tweak increases the size of the windows in the Alt +TAB screen which is really useful is if you use that tool a lot.

With more tweaks I am finding more useful tools for Windows Vista, customizing it to my usage.
