Early version of Windows NT introduced at largest Developers Conference ever

Mayor declares week of July 6 Software Developer Week

San Francisco -- July 6, 1992 -- (Business Wire) -- Monday, a capacity audience of more than 4,000 software developers from around the world gathered at the Microsoft* Win32* Professional Developers Conference for a first look at the Windows NT* operating system.

In honor of the event, San Francisco mayor Frank Jordan declared the week of July 6 Software Developer Week.

Windows NT, the new 32-bit operating system from Microsoft, creates new opportunities for Windows by coupling the ease of use of the Windows* 3.1 operating system with the computing power of today's workstation, mini and mainframe systems.

Designed for advanced users with high-end computing needs, Windows NT is expected to be released by the end of this year.

All conference attendees will receive the Win32 API preliminary Software Developers Kit (SDK) for Windows NT. It contains all the software tools and documentation that independent software vendors (ISVs) and corporate developers need to design applications to run on the Microsoft advanced Windows NT operating system, and it includes an early release of the Windows NT operating system itself.

"The Win32 SDK marks a tremendous opportunity for developers, and a major milestone for Microsoft," said Paul Maritz, senior vice president of the systems division at Microsoft. "We expect thousands of developers to make the commitment to 32-bit Windows NT because it is the most powerful, easy-to-use and scalable platform for an enormous range of applications.

Thanks to this kit and other software tools announced at the developer's conference this week, there should be a wide array of advanced software ready when Windows NT is released."

Extending Windows to Broader Capabilities

The Win32 API preliminary SDK for Windows NT provides application developers with access to the broader capabilities of the Windows 32-bit application programming interface (API).

Using the Win32 preliminary SDK, developers can write mission-critical, line-of-business and workgroup software to run on the desktop. These applications will perform complex tasks such as inventory management, financial trading and modeling, and online transaction processing, which were previously limited to mini and mainframe computing.

The Win32 SDK provides all the advanced features - such as preemptive multitasking, multi-threading, 32-bit flat memory, interprocess communication, scalability and security - that developers of these sophisticated applications require.


The Windows NT operating system is designed to run on a wide range of computer systems and networks, including powerful, symmetrical multiprocessing servers. Applications written to the Win32 API will be source-compatible between 32-bit Intel* systems, RISC systems and multiprocessor systems.

This compatibility allows developers to offer a scalable Windows- based solution for the variety of hardware that commonly exists in today's distributed computing environment - from laptops to the most sophisticated PCs.

Existing applications for Windows and MS-DOS* will also run under Windows NT, transparently taking advantage of the increased processing power.

Familiar, Consistent Environment for Development and Use

Programmers of applications for Windows 3.1 will immediately be familiar with the Win32 API and development environment. The Win32 API offers a widened, 32-bit implementation of the Windows 3.1 API, and the development environment is based on Microsoft C/C++ 7.0.

Because it is consistent, the development environment makes it simple to transition 16-bit Windows-based applications into 32-bit Windows-based applications. In addition, in the 32-bit environment, developers create new applications more quickly and easily, helping to increase their productivity.

Applications written for Windows NT also maintain the familiar interface of the Windows operating system, with its graphical design and ease of use. Users and developers can continue to take advantage of the thousands of applications and software tools and utilities developed for Windows.

By continuing to use the familiar Windows environment, organizations need not incur the additional costs associated with training for and supporting a new computing environment.

SDK Contents, System Requirements, Availability and Pricing

The Win32 preliminary SDK for Windows NT includes preliminary versions of the Win32 SDK tools, a C/C++ compiler, and the Windows NT operating system software.

Free updates to the Win32 SDK tools and to the Windows NT operating system will be sent automatically when completed. The Win32 SDK is available only on CD-ROM.

Due to the greater computing power needed for designing and testing software, developer system requirements include an 80386 33 MHz CPU (or higher), 12 MB total RAM (16 MB recommended), a CD-ROM drive, and a total of 100 MB available hard disk space for complete installation of the operating system, tools and compilers.

The Win32 SDK is available today to conference attendees. Developers not attending the conference may order the Win32 SDK, for shipment starting July 15. The cost of the Win32 SDK with printed documentation is $399; with documentation in electronic form only, the cost is $69.
