Something wrong with you? Original Windows 10 Technical Preview build 9860 is: 9860.0.141008-2044.fbl_release_cliententerprise_vol_x64fre_en-us_0b5133ad911f25dacf3d880651a0324b8c9930b5.esd and not an ISO. I Didn't told in any means that an ISO exist as original, just as an home brewed one! I just talked about MS ISO's in general! Don't read something what were not said! And just to note: What didn't exist is build 9840, it's: 9841.0.140912-1613.FBL_RELEASE_CLIENTENTERPRISE_VOL_X64FRE_EN-US.ISO!!
