There's no point to repeat same thing over and over. 16299.15 from 16299.0 was never a cumulative update; it was pushed as full edition upgrade.
To keep these build threads uncluttered towards RTM time we should have a separate thread titled Build XXXXX.xx, Is it is, or is it not, RTM?
Same by me downloaded Windows 10 Enterprise all versions in a iso image 17133.1 and activated with mak key
if remember correctly they released 16299 the first day and next day they released the .15 maybe happend the same this week..
Unless they have compiled something that we don't know anything about I hardly doubt we'll get any new builds. Easter holidays starts tomorrow, many companies works for just half the day today and easter lasts until 03th of April and if the aim is to have Spring Creators Update publicly available by the 10th of April they are pretty much out of time.
Is it just me or is the microphone dead in this build? I can only choose to "Listen" to myself in Microphone options, no program records my audio, I tried GoldWave and Discord, they don't recognize any sound.
