Microsoft has now started rolling out the Windows 10 Fall Creators Update (build 16299.15) to Insiders in the Release Preview ring, confirming our original report that build 16299.15 is indeed the RTM (Release To Manufacturing) build of the Fall Creators Update.

Insiders in the Release Preview ring should expect a larger than usual update, as this is the entirety of the Fall Creators Update being downloaded and installed. Microsoft is testing the upgrade path from the Creators Update to the Fall Creators Update with Insiders in the Release Preview before official rollout on October 17.

As part of final preparations for the general availability of the Windows 10 Fall Creators Update on Oct. 17th, we have begun releasing Build 16299.15 to Windows Insiders in the Release Preview ring.

Microsoft says that this build is rolling out slowly, so if you're in the Release Preview ring and don't yet see this update, be patient! This update should be available to you very soon. In the meantime, if you aren't yet ready to upgrade to the Fall Creators Update, make sure you leave the Insider Program to avoid getting upgraded.

The Release Preview ring is the very last ring a build goes to for testing before it rolls out to the public. This is why a build moving to the Release Preview ring is significant. It means that this build is going to eventually roll out publicly, and that it needs to be tested with a wider group of Insiders before going live.

If you're in the Release Preview ring and haven't been keeping track of all the new changes Microsoft has been working on over the last few months, check out our complete changelog for the Fall Creators Update. Build 16299.15 will be giving you all those new features and enhancements to enjoy.

Are you in the Release Preview ring? Let us know if you're getting the update to the Windows 10 Fall Creators Update build 16299.15 already.

  • ...a larger than usual update, what's the size of this thing? More than the usual 3GB I guess.
  • Well it's not a cumulative update, so yes, it's bigger than usual.
  • Quick question, will the ISOs released for Insiders be the exact same copy of RTM ISOs?
  • Yes, the image will be the full version used for public release, the same one that the media creation tool will download next week
  • Which means if I clean install with that ISO, I won't be opted-in to the Insider Program when I opened my PC, correct? I really don't want to get into the program but I want to clean install 16299 as early as possible.
  • The actual build is 16299.15, but yes clean installs with it are 'rtm' installs, so no Insider opt-in.  
  • I'm on Release preview but have temporarily stopped updates as I want to upgrade using the ISO image rather than through Windows update
  • Why is that?
  • It seems more stable and cleaner upgrading with an ISO. I've reinstated updates but the new version hasn't come through yet, might take a few hours before it downloads.
  • Time to Engage! 
  • Just went through the expected update content and found nothing of interest. Pretty boring really..
  • Still no Files On Demand unless you're in the fast ring. Disappointing.
  • It is exactly the same build as fast ring so you should have files on demand. I did have a couple of computers that had problems a few builds ago with getting files on demand and ended up just doing a reinstall through the update and recovery screen, which fixed the issue. It is very possible that something glitched on your update which is causing files on demand to not show up.
  • Files On Demand only works in the Fast Ring. Any other ring and the feature goes away. Return back to Fast and the feature returns.
  • Tell that to my two desktops, my Surface 3, Lenovo Yoga Book, and Kangaroo PC. All were on fast ring to get the update and all were moved to Release Preview and still have Files On Demand.
  • Is this 1703?
  • No, it's 1709.
  • Thanks. Downloading 1703 on my L640 and L950....
  • Why are you downloading 1703 now? Download 1709 ... Switch to Fast Ring and update
  • I rather get it thru Phone Update. I have done that before - switching to fast ring, download and switch back to Production - but my experience is MS does not want to switch you back right away, and keep you on fast, slow or RP rings for a while even though you are technically no longer part of the Insider Program!!!
  • Nice, but ugh. Why did I just waste the bandwidth on the cumulative update a few hours ago. lol. Jeesh
  • The .674 update is preparing Windows for the next feature update, without it your Windows might not even be seeing the upgrade. If your Windows is seeing it, without the patch, you are almost guaranteed to experience a larger amount of post-upgrade bugs if you do the upgrade without the patch.
  • Ooh! W10 is so cool! I take it everywhere with me. Not! MS has now become irrelevant when it comes to the wow factor (maybe except xbox). I bet the next thing to go under Ne-dull-a will be hololens. 
  • Then why are you wasting your time here?  Go hangout in the community of your preferred platform and stop wasting our time.
  • He's just trolling
  • Trolls belong under a bridge. Not on windows Central. Go bother some billy goats.
  • Answering the author: I have one machine on release preview, it is in Denmark and is not yet receiving it. This is quite normal, as this usually take anywhere from 6 hours to 3 days, before it sees a new larger build. The machine is custom build and uses an old AMD processor.
  • Switch to fast ring, get the update and then switch back to release preview.
  • Thank you for the tip, but I was just replying to the author's question ^_^
    Besides, I have a feeling Microsoft would want me to test the upgrade path without jumping rings 😊
  • This upgrade infected my system last night. It has destroyed the Edge browser and the entire Solitaire collection. Why on earth does MS release garbage??? why???
  • Because Nadella,  Thats why!  If it's not cloud or linkedin,  he gives two ***** about it.
  • THe last update killed Cortana's ability to hear the microphone on my Surface Pro (the original one) so I had to roll back. I think I might wait on this one for the release....
  • Same for my Elitebook X360. :(
  • It might be a good idea to wait. Touch scrolling doesn't work for the action center unless you specificallly touch the whitespace (which is pretty difficult). Already 105 votes spread out several reports in the feedback hub, with MS noting that they're "looking into it". I'm going laugh if MS releases this version to Production next week because it's pretty buggy in tablet mode.
  • Please HELP the ones that created the FEATURED Enterprise update 1703, it's over 3 weeks and the update WON'T install. It goes through 2 update install, reboots starts update install gets up to 30% then powers off the PC. The ones that created it needs it redone by SMARTER people.
  • On my 950XL, this broke my contacts from syncing. I have all my contacts in my Outlook.com profile which is the phone's primary account. None of the contacts are on the phone but they are all still online. When I go to People and click settings, it says my Outlook.com account needs attention but when I touch it, it doesn't take me anywhere to fix it. WTF
  • Got it on my desktop and Surface Pro this morning in Australia.
  • Does anyone know - if I move apps to a different drive/partition, will they be preserved when I clean install the Windows system drive? Trying to avoid re-installing all the apps if possible. I know some can't be moved but most of those are the Inbox apps
