Windows 11 Version 25H2 ISO Is Now Available

When Microsoft brought Windows 11 version 25H2 to the Release Preview channel almost two weeks ago, it said it would release ISOs the following week. It later delayed those releases, but the x64 version is available today.

“The ISOs for Windows 11 version 25H2 are now available for download,” a brief update to the Release Preview announcement post reads.

Because 25H2 isn’t yet in stable, the ISO can be downloaded from the Windows Insider Preview Downloads website. There are two versions, one for x64 for the Release Preview version of the ISO, and one for Arm64 that’s from the Dev channel (and is a VHDX file for Hyper-V:

• x64: Windows 11 Insider Preview (Release Preview Channel) – Build 26200
• Arm64: Windows 11 Client Arm64 Insider Preview (Dev) – Build 26200

I can confirm that the x64 ISO is for build 26200.5074, which is the Release Preview version, of course. But it’s not clear what the Arm 64 build is. I will try to figure that out Thursday.
