Nope... They were very mysterious... Maybe they've just started looking into it as 3.6 has only just been released... 
I suspect they are only going to start looking at it once they get the RTM. Many manufacturers have that policy (only a few early birds catch the worm I notice).

Microsoft just updated their update on the Windows Insider policy with respect to licensing. The only real clarification here is that they explicitly state that once you opt out of the program, you have to qualify for the free upgrade offer or pay for a license.
 
“I want to continue as a Windows Insider!” If you want to continue as a Windows Insider past 7/29 there is nothing you need to do. You’re already opted in and receiving builds in the Fast or Slow ring depending upon your selection. This is prerelease software and is activated with a prerelease key. Each individual build will expire after a time, but you’ll continue to receive new builds so by the time an older prerelease build expires you’ll have received a new one. Since we’re continuing the Windows Insider Program you’ll be able to continue receiving builds and those builds will continue to be activated under the terms of the Windows Insider Program. We provide ISOs for these builds for recovery from any significant problems, but they are still pre-release software. As part of the program we’ll upgrade Insiders to what is for all intents and purposes the same build as what other customers will get on 7/29, but that will be just another build for Insiders, and those who stay in the program will simply get the next build after as well.
 
“I want to opt out of the Windows Insider Program on 7/29.” If you decide to opt-out of the program and upgrade to the 7/29 build you will be subject to exactly the same terms and conditions that govern the offer* that was extended to all Genuine Windows 7 and 8.1 customers. This is not a path to attain a license for Windows XP or Windows Vista systems. If your system upgraded from a Genuine Windows 7 or Windows 8.1 license it will remain activated, but if not, you will be required to roll back to your previous OS version or acquire a new Windows 10 license. If you do not roll back or acquire a new license the build will eventually expire.

So it's not Windows 10 for free.  It's continuing access to beta versions.
 
I can't run my studio on beta versions...

Well, it is Windows 10 for free, right? And you can opt out of updates and stay on a specific build if that's what you want to do, but that's not really the point of the program. But to your point, yeah, I wouldn't recommend anyone bind Insider program builds to a machine that they depend on for a stable DAW, those folks just aren't prepared to spit in the face of death.

But if you do your authorization code will expire,  so no free Win 10.

Oh yes, that's right.

Downloading build 10159 right now...
I've been running Platinum, PT 12 (now PT12.1), S1-3, and a lot of others without issue...

Me too, and it's out today after releasing 10158 yesterday. Microsoft's getting as good as Cakewalk!
 
To all insiders, build 10158 is an incredible build. Most of the debug code has been removed and it's extremely fast, smooth and responsive and there's a great deal of polish that's been applied since 10130, my most recent experience. Sonar and my venerable 10 year old MOTU 8pre have been functioning flawlessly. I'm really beginning to like Windows 10 quite a lot. Now some of the utility apps are kind of lame and dumbed down (Mail, you know who I'm talking about!) but its a great build overall. Even the new browser, Microsoft Edge works great and I am a skeptic on that thing.
 
So now I'm installing 10159 and hope to have just as sunny a report as I did for 10158. The saga continues.

just updated mine.....working fine

Smooth as silk ....yeah...

I haven't tried X2 or other pre- membership versions but to my mind the only roadblock you might find would be in your interfaces' drivers.

Preview versions coming "hot and heavy" now.  10162 released yesterday.

Since I had win 8.1 I could opt out and be fine, I just like seeing the new stuff, and my system isn't "critical".

I had some issues with audio on 10162, no audio devices were seen but ASIO worked. I uninstalled all the audio drivers, rebooted and reinstalled and it's working well now. This is a pretty polished build compared to even 10130. And it seems quite a lot faster than 10130 as well.

Build 10130 totally trashed my old DAW that I was testing Win 10 on.  To the point that when I tried to use the ISO to do a clean install, it kept on trying to install on my E drive.  But that's beta software.  I did managed to rebuild the PC but had to go back and wipe the drive, reformat it and install XP, then the Win 7 upgrade.  I'm going to try to take the opportunity to put in some larger HD that I salvaged from another old PC and give it a go with build 10162.

By the way, the issues I've had throughout the preview program with the various releases have been numerous and very frustrating (I keep muttering "I signed up for this, I signed up for this..."), and I've posted about 50 feedback items to the program. Sonar, however, has worked pretty flawlessly throughout the experience on even the crankiest of builds, and while my mail or my browser may have crashed uncontrollably, Sonar kept pumping right along, and my creaky old MOTU firewire interface has worked great even with the in-the-box firewire drivers (no legacy driver installs.) For DAW's this OS is looking pretty promising. I'm looking forward to seeing some DAW benchmark numbers.

Failed again but think I might have found the solution here:

Trying the update again.

Good to hear you got it going! You should see the update right away if you're fast ring. I think I read that they are pushing 10162 to the slow ring.
