Powerful new calculator in Windows 7

The Windows 7 has some hidden depths. It includes plenty of unit conversions such as length and weight, while you can also do date-related calculations such as working out the number of days before a certain date.

In addition, there are ready-to-go Worksheets for vehicle economy, leasing costs and mortgage calculations. The main menu also gives you powerful new Statistics and Programmer modes.

The treatment of the calculator is typical of how many standard Windows applications have been given new life.
