Everything about AARD code

Segment of code in beta release of Windows 3.1

The AARD code was a segment of code in a beta release of Microsoft Windows 3.1 that would issue a cryptic error message when run on the DR DOS operating system rather than the Microsoft-affiliated MS-DOS or PC DOS. Microsoft inserted the code in an attempt to manipulate people into not using competing operating systems; it is an example of the company's fear-uncertainty-doubt tactics. Wikipedia →
