Download links for Windows 11 25H2 ISOs now available before official Microsoft release

Windows 11 version 25H2 ISO and eKB download links are now live before the official announcement from Microsoft is made.

Earlier this month, Microsoft published Windows 11 25H2 ISOs on the Release Preview channel for Windows Insiders. As such, we knew that it was only a matter of time before Windows 11 version 25H2 would hit general availability status.

The company it seems is working on just that and ISO images for the same have since been uploaded to its delivery servers. A Reddit user -TekkieBoy- spotted these and extracted the download links for Windows 11 25H2 for x64 and Arm64.

Microsoft already confirmed that Windows 11 25H2 will not be a full OS swap, unlike 24H2. Instead, the move from version 24H2 to 25H2 will be more like what happened on 23H2 when users upgraded from Windows 11 22H2. Version 25H2 will be delivered as an enablement package (eKB).

According to Microsoft, 25H2 and 24H2 "share the same core operating system and identical system files." So the latest monthly quality update for 24H2 will have 25H2’s new features, but they will simply remain dormant until activated, which can be done via the eKB, a small, quick-to-install update that acts as a "master switch". Thus the eKB essentially enables the new dormant features. Once applied, it upgrades 24H2 to 25H2 with a single restart thus reducing system downtime.

Thus you can download the necessary eKB (KB5054156) if you are already on the latest 24H2 cumulative update, to in-place upgrade to 25H2 without downloading the entire ISO:

Keep in mind though that Microsoft has not yet announced the release of these and thus these are not intended to be downloaded in its current state, there could be issues.

Thanks for the tip, Aryeh!!
