Microsoft announced today its all-new Windows 11 software for PCs. In an exclusive interview with WSJ’s Joanna Stern, Microsoft CEO Satya Nadella spoke about the new operating system, called out app stores, and invited iMessage to the Microsoft Store.

While Nadella seems optimistic about a future where all developers and apps are welcome to the Windows software, no matter what, Apple has taken a different path.

Mostly during the last year, Apple has been accused of monopoly over the iPhone App Store. There’s the Epic lawsuit, as well as many other governments that want to break Apple’s App Store. Even the U.S. Congress wants the iPhone to be sold without any pre-installed app, although it seems a stretch.

Microsoft CEO Satya Nadella reinforced that Windows welcomes more marketplaces to its ecosystem:

Joanna Stern asked Nadella about integrating Microsoft software and services with the iPhone, in which he replied:

“We have the ability to have multiple marketplaces. We want to have a great marketplace, but we also welcome other marketplaces.”

Here’s everything Microsoft announced during the Windows 11 event.

“We’d love to make sure that it works better, we do everything we can. Like anything Apple wants to do with Windows rather it’s iTunes, iMessage, or whatever, we welcome that. But, overall, we want to make sure our software runs great on Apple devices.”
