Windows 8.1 build 9385 has leaked which is the fourth copy of Windows 8.1 to make its way to the web, well ahead of Microsoft's expected release in June and closely following behind the leak of build 9375.

Links are currently available that are of the build 9385 of Windows 8.1 that will be released later this year. As with any leak, we highly caution you from installing the build on your primary machine as these builds are likely not stable and could corrupt any disk you install the files on.

We have already seen one new feature leak from this build, an alarm app setting, but once this build gets into the hands of many, we will surely discover more features Microsoft will bring with the 8.1 upgrade.

The previous builds to leak were 9374, 9369, and 9364. Seeing as this is only a small incremental increase from the last leak, we don't expect to see many changes in this build. With that said, Microsoft could introduce a new feature with each new build so there may be small changes hidden within this copy of Windows 8.1

Microsoft is expected to release a preview build of the platform in late June as part of its upcoming BUILD conference with the RTM release coming sometime in the late summer season.

As standard practice for Neowin, we will not link to the locations that contain the leaked builds.
