Microsoft has officially announced that Windows 11 25H2 is on the horizon, bringing with it an intriguing blend of continuity and enhancement. This upcoming upgrade is set to be more of a feature enablement exercise than a complete overhaul, as Windows 11 24H2 and 25H2 share the same underlying source code.
Feature Enablement and Compatibility
Last week, Windows Insiders gained early access to 25H2, marking it as this year’s annual feature update. For those anticipating a transformative Windows 12 to alleviate the challenges posed by 24H2, disappointment may be in store. Instead of a fresh start, Windows 11 25H2 will essentially build upon its predecessor, introducing additional features that Microsoft can activate through an enablement package.
Jason Leznek, Principal Project Manager for Windows Servicing and Delivery, emphasized the seamless compatibility between the two versions: “Windows 11, version 24H2 and version 25H2 share the same source code, with only the additional features turned on.” He advised that while testing is still essential, the focus should shift towards the new features rather than a comprehensive review of the operating system, applications, or device compatibilities.
Given the challenges faced by Windows 11 24H2 since its release in 2024, this approach is reassuring. The Windows Release Health Dashboard indicates that the operating system has encountered a series of issues, prompting Microsoft to implement compatibility holds related to both software and hardware problems.
On a positive note, the shared code base ensures that any functionality that thrived on Windows 11 24H2 will seamlessly transition to 25H2, while any existing issues will persist.
Changes Ahead: BSoD Replacement and Enhanced Security
The rollout of Windows 11 25H2 to Insiders coincides with significant news regarding the notorious Blue Screen of Death (BSoD). Following the 2024 CrowdStrike incident, which saw a faulty update from the cybersecurity vendor crash numerous Windows systems, Microsoft has decided to retire the BSoD. This infamous screen will be replaced by a black “unexpected restart” screen, although users will still be able to view the stop error code at the bottom.
In addition to this visual change, Microsoft is also introducing quick recovery options for PCs that struggle to restart successfully. In response to the CrowdStrike debacle, the company is enhancing its security framework by allowing antivirus and endpoint protection vendors to operate in user mode, outside of the Windows kernel.
This replacement for the BSoD is expected to roll out on Windows 11 24H2 devices over the summer, making it a key feature of Windows 11 25H2 as well. Furthermore, the Windows endpoint security platform, designed to facilitate the transition of antivirus and endpoint protection vendors out of the Windows kernel, will enter private preview in July.
