I don't know if language pack makes any difference but I've been running 14257 since it was released 10 days ago, EN_US with EN_CA language pack
Just open a CMD as Admin and use the command: slmgr /dlv and wait for the new windows appear, capture that and post it on this forum. Thanks.
Hey man, he is not a insider, he did winver and got this: no time 10586.104 original Windows 10.My esd 14257 cs_CZ delete
I know that! Just, for to get real infos what he have, the screenshots from SLMGR would show that. Also it will show what version (Pro/Home/VL/Enterprise) he has installed already (of the older version)! You and I, and everybody else know, how mnay uncorrect infos are posted, which leads to bad discussion etc., so to get real infos are essential!
I doubt he knows what a screenshot is or how to make one, he's just got a regular copy of Windows 10, lol And I do not speak his language to tell him how?
