@Former Member, POC appears to be WORKING after cursory testing.
Previously, within 3 minutes of boot time, ENS would set incorrect productState to 393232, always, without fail.
CURRENTLY with latest POC_WindDef (Platform build 1803, TP build 1858), within 3 minutes of boot time, ENS still seems to update WMI as evidenced by "timestamp", but productState IS CORRECT (397312).
Updating my SR with findings.
I've gotten conflicting information about whether the POC would be included in the 10.7 December updates... At first I believe @Former Member told us they wouldn't, but then my SR technician indicated that possibly it would... fingers crossed.
