Microsoft announces Windows 11 Version 25H2

Roll out of first Insider Preview build gives early testers a glimpse into update

Microsoft is doubling down on Windows 11, unveiling a new version – Windows 11 version 25H2 – slated for general release later this year.

Microsoft has officially confirmed that its next operating system release will not be Windows 12, at least not anytime soon.

Instead, the tech giant is doubling down on Windows 11, unveiling a new version – Windows 11 version 25H2 – slated for general release in the second half of 2025.

The announcement, made on Friday, was accompanied by the rollout of the first Insider Preview build, giving early testers a glimpse into the upcoming update.

"Today, Windows 11 version 25H2 became available to the Windows Insider community, in advance of broader availability planned for the second half of 2025," said Jason Leznek, Principal Product Manager at Microsoft, in a post.

The confirmation quells months of speculation about whether Microsoft was gearing up to launch Windows 12. Instead, the company signals a more incremental approach, with 25H2 building directly on the foundation of version 24H2-using the same platform release and servicing stack.

As a result, the update process will resemble a standard cumulative update, allowing users to upgrade with a simple restart, rather than undergoing the extensive system file replacement required between earlier builds like 23H2 and 24H2.

Features to be added gradually

So far, the 25H2 Insider Preview appears to contain no exclusive features, according to TomsHardware. It’s changelog is nearly identical to that of the latest 24H2 Beta Channel release.

However, Microsoft confirmed that new functionality will be gradually developed for 25H2 and pushed to previous builds as well.

Leznek explained the process, noting that "new features we develop for Windows 11, version 25H2 are part of the version 24H2 branch".

"When the new code is complete, we include it in the monthly LCUs [Latest Cumulative Updates] for Windows 11, version 24H2 in a Disabled state," he stated.

This shared platform model is not unprecedented. Microsoft has previously maintained similar arrangements between Windows 11 version 22H2 and other updates, and also during the Windows 10 era.

Microsoft also revealed the official support lifecycle for Windows 11 version 25H2, which varies by edition:

1. 24 months of support: Windows 11 Home, Pro, Pro Education, and Pro for Workstations
2. 36 months of support: Windows 11 Enterprise, Enterprise multi-session, Education, and IoT Enterprise

Coinciding with the 25H2 preview release is a significant user experience shift – phase out of the infamous Blue Screen of Death (BSoD).

Long a symbol of system failure, the blue screen gained renewed notoriety during the 2024 CrowdStrike fiasco, when a defective security update crashed countless Windows machines globally.

Though Microsoft and CrowdStrike swiftly retracted the update, the damage left a lasting impression.

In response, Microsoft is introducing a black "unexpected restart" screen that will replace the BSoD across devices running 24H2 and later, including 25H2.

The screen will retain stop error codes at the bottom for troubleshooting, but is designed to integrate better with new recovery tools.

Microsoft is also prioritising system resilience by developing quick machine recovery mechanisms for cases where PCs fail to reboot successfully. This includes new tools that allow antivirus and endpoint protection solutions to operate in user mode, isolating them from the sensitive Windows kernel.

These kernel-isolating tools will enter private preview in July as part of Microsoft's evolving Windows endpoint security platform, with broader integration expected in future updates.
