The Daily Cycle for Windows 2000
By Microsoft.

This video documentary walks you through the daily cycle of testing new Windows operating system before the release of a new version of the software. It is very interesting to see the chalenging amount of work involved before the software is sent to the market. We recommend all the fans to watch this so that you can see by yourself that Microsoft cares about the quality of products it sells to its customers, including us, the fans.
