Windows 11 25H2 ISOs Now Available for Insiders with New Features
▼ Summary
– Microsoft released ISO install media for Windows 11 version 25H2 on September 10, available via the Windows Insider download page for testers.
– The update is delivered as an enablement package that installs over the existing 24H2 base, following the same approach as previous fall updates.
– The ISO allows testers to perform in-place upgrades or full reinstalls, providing more control over the update process.
– 25H2 includes under-the-hood changes like the ability to uninstall certain Microsoft Store apps on managed devices and removal of deprecated tools.
– Support for 25H2 will begin at general availability, likely in October, resetting the update clock for those who adopt it early.
Microsoft has officially launched ISO installation media for Windows 11 version 25H2, offering Windows Insiders a direct path to test the upcoming feature update before its public debut later this year. Available for download as of September 10, these files allow users to perform clean installations or upgrades without relying on Windows Update, providing greater flexibility for early adopters and IT professionals.
This latest build, identified as 26200.5074, initially reached the Release Preview Channel on August 29. Microsoft has clarified that the update functions as an enablement package, meaning it layers new features onto the existing 24H2 foundation rather than introducing a completely new build. This streamlined approach mirrors the company’s strategy with previous fall updates like 22H2 and 23H2, resulting in smaller download sizes and faster installation times while preserving core system stability.
With the ISO now accessible, testers can choose between an in-place upgrade by mounting the file directly or performing a full system reinstall using bootable media created via tools such as Rufus. The download itself is approximately 7 GB, though exact sizes may vary based on language selections.
While 25H2 doesn’t introduce sweeping visual changes, it includes meaningful refinements aimed at improving system management and security. Enterprise and Education editions now allow administrators to uninstall a predefined set of Microsoft Store applications, simplifying device customization for organizational use. Outdated components, including PowerShell 2.0 and WMIC, have also been phased out to reduce potential security risks.
It’s important to note that official support for version 25H2 will commence at general availability, not during the preview phase. Since the 24H2 update only receives 24 months of updates (extended to 36 for Enterprise and Education users), adopting 25H2 effectively resets the support timeline. This means testers installing the preview now will benefit from an extended period of future updates and security patches once the version is officially released.
Although Microsoft has not announced a specific launch date for the general rollout, historical patterns suggest an October release window, consistent with the company’s annual update rhythm.
