The company has said no more preview builds of Windows 10 21H2 will be released over the next few weeks, meaning users won't receive any early looks at new features, services or tools.
The news comes as Microsoft is heavily expected to unveil the next generation of its software, possibly called Windows 11, at an event on June 24.

Windows 11 incoming?
The news was teased in release notes of what could be the latest Windows 10 Insider Preview Build for some time.
The notes for Windows 10 Insider Preview Build 21390, which the company admitted "does not include anything new and is designed to test our servicing pipeline", suggest that Microsoft is preparing for a heavy amount of stress on its servers in the near future.
"Over the course of the next several weeks, our focus will be on releasing multiple Cumulative Updates on top of Build 21390," Microsoft wrote. "Having Insiders on the Dev Channel testing this will be of great help to us and we will be releasing updates as before very soon!"
The June 24 Windows event should tell us much more about the future of Windows, ahead of the Sun Valley revamp emerging later this year, with apparently revolutionary changes in terms of the overall look and interface.
Rumors are building that Microsoft will be releasing a whole new version of Windows - the aforementioned Windows 11 - rather than just a cumulative update to its software.
Microsoft has said that its new release is the “most significant updates to Windows of the past decade” - but little else is known about the upcoming software, hence the company's apparent desire to make sure nothing leaks out.
