From Kim Komando :
Windows is a great operating system. However, there is always room for improvement.
I often receive complaints about little annoyances in Windows. Some people are irritated by the Caps Lock key. Others have problems working with multiple windows.
There isn’t much you can do about these annoyances. That is, until now. Pistachio is a program that will help you customize Windows.
Once you download it, you can change the way Windows works with windows. You can also disable certain keys or change the look of icons.
These customizations may not appeal to everyone. But give Pistachio a try. If you don’t like it, delete it. There is no messy uninstall process!
