If you own a PC, chances are it’s running Windows, the operating system that Microsoft has offered since 1985.
Even with people buying modern Macs with energy-sipping Arm chips, and even with some students and corporate workers picking up Chromebooks during the pandemic, Windows still holds on 83% market share for personal computers, according to technology industry research company Gartner. It’s been in the pole position uninterrupted since Gartner kept keeping track in 2000, and probably for at least a decade before that as well.
Today Windows represents 14% of Microsoft’s total revenue, and historically Windows has been more profitable than other parts of the $2 trillion company. When Windows grows, Microsoft benefits.
So the company is once again refreshing Windows with the announcement of Windows 11 on June 24. New system requirements might cause some people to purchase new PCs capable of running Windows 11, and that would boost Microsoft’s Windows franchise.

The Windows track record hasn’t always been perfect. It took a few releases to gain popularity over its character-based predecessor, DOS. Some versions, including Windows Vista and Windows 8, were poorly received. And when smartphones emerged in the 2000s, and Microsoft wasn’t able to achieve the same pervasiveness as it did on PCs. “We missed the phone wave,” said Yusuf Mehdi, a corporate vice president who has been at Microsoft for almost three decades.
But over the years Microsoft made Windows easier to use, with additions such as the Start menu, and made upgrades free. And because many organizations have become used to deploying Windows alongside other Microsoft products, it’s natural for them to stick with Windows. And so Windows has managed to keep growing.
Microsoft wants to keep it that way. It’s adding one of the features of Chromebooks — Android apps — to Windows 11. Stores will stock PCs featuring the new release in time for the holiday season.

CoreWeave shares fell about 6% in extended trading on Tuesday even as the provider of artificial intelligence infrastructure beat estimates for second-quarter revenue
Here’s how the company did in comparison with LSEG consensus:
Earnings per share: Loss of 21 cents
Revenue: $1.21 billion vs. $1.08 billion expected
Revenue more than tripled from $395.4 million a year earlier, CoreWeave said in a statement. The company registered a $290.5 million net loss, compared with a $323 million loss in second quarter of 2024. CoreWeave’s earnings per share figure wasn’t immediately comparable with estimates from LSEG.
CoreWeave’s operating margin shrank to 2% from 20% a year ago due primarily to $145 million in stock-based compensation costs. This is CoreWeave’s second quarter of full financial results as a public company following its IPO in March.
CoreWeave pointed to an expansion in business with OpenAI, a major client and investor. Also during the quarter, CoreWeave acquired Weights and Biases, a startup with software for monitoring AI models, for $1.4 billion.
In May, management touted 420% revenue growth, alongside widening losses and nearly $9 billion in debt. The stock still doubled anyway over the course of the next month.
CoreWeave shares became available on Nasdaq at the end of the first quarter, after the company sold 37.5 shares at $40 each, yielding $1.5 billion in proceeds. As of Tuesday’s close, the stock was trading at $148.75 for a market cap of over $72 billion.
A CoreWeave data center project with up to 250 megawatts of capacity is set to be delivered in 2026, the company said in the statement.
Executives will discuss the results and issue guidance on a conference call starting at 5 p.m. ET.

The Trump administration is still working out the details of its 15% export tax on Nvidia and AMD and could bring deals of this kind to more companies, the White House’s Karoline Leavitt said Tuesday.
“Right now it stands with these two companies. Perhaps it could expand in the future to other companies,” said Leavitt, the White House’s spokesperson.
“The legality of it, the mechanics of it, is still being ironed out by the Department of Commerce, and I would defer you to them for any further details on how it will actually be implemented,” she continued.
President Donald Trump confirmed on Monday that he had negotiated a deal with Nvidia in which the U.S. government approves export licenses for the China-specific H20 AI chip in exchange for a 15% cut of revenue. Advanced Micro Devices also got licenses approved in exchange for a proportion of its China sales, the White House confirmed.
“I said, ‘If I’m going to do that, I want you to pay us as a country something, because I’m giving you a release,'” Trump said Monday.
“We follow rules the U.S. government sets for our participation in worldwide markets,” Nvidia said in a statement this week.
Trump said the export licenses for AMD and Nvidia were a done deal. But lawyers and experts who follow trade have warned that Trump’s deal may be complicated because of existing laws that regulate how the government can charge fees for export licenses.
The Commerce Department didn’t immediately return a request for comment.
The H20 is Nvidia’s Chinese-specific chip that is slowed down on purpose to comply with U.S. export relations. It’s related to the H100 and H200 chips that are used in the U.S., and was introduced after the Biden administration implemented export controls on artificial intelligence chips in 2023.
Earlier this year, Nvidia said that it was on track to sell more than $8 billion worth of H20 chips in a single quarter before the Trump administration in April said that it would require a license to export the chip.
Trump signaled in July that he was likely to approve export licenses for the chip after Nvidia CEO Jensen Huang visited the White House.
The U.S. regulates AI chips like those made by Nvidia for national security reasons, saying that they could be used by the Chinese government to leapfrog U.S. capabilities in AI, or they could be used by the Chinese military or linked groups.
The Chinese government has been encouraging local companies in recent weeks to avoid using Nvidia’s H20 chips for any government or national security-related work, Bloomberg reported on Tuesday.
