A Chinese leaker has posted the ISO image for 64-bit (x64) Simplified Chinese (zh-CN) version of Windows 10 Build 10151 onto the Internet, similar to the originating source of how Windows 10 Build 10147 was leaked. However, this time, the leaked ISO is of Simplified Chinese version, which is the language widely used in China itself.

The leaked Windows 10 Pro Build 10151 of GVLK has the build string of 10151.0.150617-1826, and is from fbl_impressive, the branch which almost all leaks came from.

Windows 10 Pro Build 10151 File Information

File Name: 10151.0.150617-1826.FBL_IMPRESSIVE_CLIENTPRO_VOL_X64FRE_ZH-CN.ISO
MD5: C45F6E1C6066C655FA2665AA30FB5BE0

Unfortunately, no en_US English language pack is available to convert the ISO to English yet, although some hack has started to appear in the form of homebrew ISO which integrated English language pack from Windows 10 Build 10154 and registry trick. And WZOR, the famous Russian leaker, apparently has Windows 10 Build 10154, but does not yet leak it.

Update: Windows 10 Build 10158 (official release)
