Thanks for pointing this out Brian. This morning I attempted to push a SEP new 12.1.6 install to a fully updated Win 10 machine.The install kept failing per the Window's application log.
I then created an install package and tried that. The install would start and shortly into the install it would just hang at 0%.
This type of incident has been my biggest fear as Microsoft continually makes changes to Win 10. When i get a chance later today I will try the workaround in the KB article.
This information should be pinned at the top of the forums as many will start hitting this bug.
