History
Version 1.0 was navigated with the use of either arrow keys or Alt and a highlighted letter. By selecting a category, additional information about it will be displayed in a pop-up window. It also lets the user see the content of system files, such as  or.

Starting with version 2.0, it also displays the installed version of Microsoft Windows (with Windows 9x operating systems being identified as their kernel version 4.xx) and a mouse can now be used to navigate through the tool. Pop-up windows now also function like windows in Windows 3.x. By clicking on the button at the top left corner, the window closes. The tool also gained a new menu bar, where most options previously seen at the lower half of the interface moved into. The CD-ROM category merged into the hard disk one, where CD-ROM drives and the installed MSCDEX version are being displayed.

Version 3.0 added support for the Pentium processor, but other than that, didn't changed much from the previous version 2.1. It's development was ceased prior to the release of Windows 95, with itself being dropped from Windows with Windows 98 and replaced by System Information.
