Safe to ignore Windows Update KB3152599 - InstaHost Solutions

There’s been a lot of noise over the weekend about a new update showing up on WSUS servers. KB3152599 (Device Access Broker ACL Update for Win10 Version 1511) is the update yet no associated KB article exists for it and there’s absolutely no additional information given.

This update should have never shown up in the normal WSUS infrastructure. The update is only intended for Insiders as part of the pre-release ring and is meant to fix an issue specific to the Start Menu in the Windows 10 upgrade process.

Microsoft is investigating why this pre-release update is showing up for normal WSUS users, but you can safely ignore it.
