[UPDATE: The draft guidance has been published here.]
We have been receiving quite a few inquiries regarding SCM security baselines for Windows 10. The baselines are currently in development, and have been for a few weeks now and we are targeting a public beta either later this month (August) or September.
The Windows 10 baseline will also include security settings for our new Edge browser, so you will be able to manage both the machine, user and now browser security settings from a single baseline.
Watch this space for updates as well as release information as to how you can participate in the public beta.
