I've got two questions regarding Insider Program: Based on askvg.com/windows-10-changelog/ there have been 5 Insider builds since the RTM release last July. So I'm asking: when are all the new features included in these builds are scheduled to reach to those that use the General Release/RTM builds? Joining Insider Program requires connecting with a Microsoft Account. I currently use a local account in build 10240 RTM, fully updated (activated via KMS since win8.1 using Microsoft Toolkit 2.6) . I'm thinking about joining the Insider program, in order to get the newest, 10576 build. If I use a Microsoft email to join that program, is this some kind of "giveaway" to Microsoft that I don't have genuine Windows, or it doesn't matter? I mean, is it considered safe? Sorry if these questions have been answered many times, but I couldn't find anything relevant.
