We’re on the Semi-Annual channel, machines are currently on build 11929.20776. We have applied several rounds of updates using BigFix. According to this page:
the June update is 11929.20838. However, BigFix is showing those machines relevant on Monthly Channel 12827.20268. I also do not see a Semi-Annual channel 11929.20838 fixlet at all, even examining the non-relevant fixlets.
