At first glance the Windows 7 calculator looks just like Vista's version, but explore the Mode menu and you'll see powerful new Statistics and Programmer views. And if you're clueless about bitwise manipulation, then try the Options menu instead. This offers many different unit conversions (length, weight, volume and more), date calculations (how many days between two dates?), and spreadsheet-type templates to help you calculate vehicle mileage, mortgage rates and more.
Don't take any Windows 7 applet at face value, then - there are some very powerful new features hidden in the background. Be sure to explore every option in all Windows applets to ensure you don't miss anything important.
