Microsoft Office and Windows Were Built on Apple and Intel, CEO Admits

Microsoft is today recognised as a software giant with a market capitalisation exceeding 3 trillion US dollars.

Yet few realise that Windows and Office’s success is fundamentally indebted to two of the company’s greatest rivals in the technology industry: Intel and Apple.

This surprising admission came directly from Microsoft CEO Satya Nadella whilst speaking at the Morgan Stanley Technology, Media & Telecom Conference 2026 earlier this month.

Nadella reflected on the company’s history, noting that past competition actually shaped the foundation of Microsoft’s current success.

Nadella highlighted Microsoft’s close partnership with Intel, which produced the dominant “Wintel” (Windows-Intel) model. According to him, without Intel’s chips serving as the brains of IBM computers, Windows would likely never have been created or dominated the market.

Even more surprising, Nadella credited Microsoft’s eternal rival, Apple.

“Without the Mac, I doubt Microsoft Office would ever have been created,” Nadella stated, according to reports from Windows Central.

In fact, Microsoft’s flagship applications such as Excel and Word with graphical user interface (GUI) actually debuted first on Apple’s Mac computers, long before they reached Windows.

This occurred because Apple’s operating system was far more visually appealing at the time compared to Windows 1.0, which remained highly rigid following the DOS era.

For Nadella, business is not a zero-sum game. The success of others does not mean failure for Microsoft, but rather an opportunity to “hitch a ride” and deliver added value to consumers.

The “software factory” vision left by founder Bill Gates, which guided the company for decades, is now recognised as insufficient for addressing today’s challenges.

The company’s core focus now rests entirely on three new pillars: artificial intelligence (AI) transformation, security, and product quality improvement.

Speaking before Morgan Stanley investors, Nadella revealed that AI has transformed how office workers operate.

He noted significant growth in document creation on SharePoint and OneDrive thanks to the Copilot assistant. On the programming side, approximately 4 to 5 per cent of code now circulating in public GitHub repositories is claimed to be purely written by AI agents.
