Apparently, this is also the last major update for 2014.

How Do I Get The New Build?

Generally, new builds are delivered automatically via Windows Update Windows Update: Everything You Need to Know Is Windows Update enabled on your PC? Windows Update protects you from security vulnerabilities by keeping Windows, Internet Explorer, and Microsoft Office up-to-date with the latest security patches and bug fixes. Read More .

You can set a time frame for automatic maintenance, i.e. a maintenance window for Windows Update to run. To do this via the Control Panel, click the Start button, search and open the Windows Update Control Panel window, click Change settings, then Updates will be automatically installed during the maintenance window. Alternatively, you can go through the modern app. Go to your Start Menu, search and open PC Settings, go to Update and recovery, open Preview builds, and click Change the time my PC installs preview builds. In the window that opens, change the time under Run maintenance tasks daily at.

During that time, your computer needs to be turned on or in Sleep mode and charging.

Why Did I Not Automatically Receive The New Build?

Either your computer wasn’t available during the maintenance window or some other conditions weren’t met yet.

Most likely, you didn’t upgrade to the Fast ring when Build 9860 came out Windows 10 Is Evolving - This Is What's New In Build 9860 The new Windows 10 version comes with several new features and provides sneak peeks into future builds. Microsoft is morphing Windows 10 right in front of our eyes. Find out where Windows is headed. Read More . With that build, Microsoft split the Windows Insider layer of its ring progression model into a Fast and Slow ring. Users in the Fast ring receive new builds immediately. Some builds are released with (known) issues, which are fixed through Windows Update shortly after. By the time users in the Slow ring receive the upgrade, usually just a few days later, most bugs have been ironed out, which adds a layer of security.

Windows Technical Preview Progression Model


To switch to the Fast ring, navigate to Preview builds in the PC Settings app (as described above and illustrated below) and select your preferred upgrade speed from the drop-down menu.

If your computer was available, you were already in the Fast ring, and you still haven’t received the update automatically, there must be other issues preventing you from upgrading manually. We’ll address those further down.

Can I Get An ISO Image To Install The New Build?

Yes! Microsoft gave in to user feedback and decided they will be offering ISO images for all new builds of the Windows 10 Preview. The catch is that those builds won’t be available until the upgrade is released to the Slow ring. The ISO images will be available via Windows Insider.


Can I Manually Get The New Build?

Yes. And here it gets a little confusing. Microsoft says the Build is distributed via Windows Update, but you can’t trigger the installation via the Control Panel. Instead, go to your Start Menu, search and open PC Settings, go to Update and recovery, open Preview builds, and click Check now.

Help! What Does This Error Message Mean When I Try To Install The New Build?

The quickest way to find an answer to this question, is to search the exact error code on Google or Bing. To prevent errors from happening in the first place, especially during installation, go through the following steps.

Free Up Drive Space

Microsoft warns:

Some systems may see disk growth of 20GB+ due to driver install duplication. On systems with low disk space this can block setup and cause a rollback to the previous build.

For that reason, it’s a good idea to always have a 20-30 GB buffer on your system drive. If you don’t currently have this amount of space available on your Windows 10 partition, you can extend your Windows partition via Windows Disk Management How To Shrink & Extend Volumes Or Partitions in Windows 7 In Windows 7 and Windows Vista, resizing your volumes or re-partitioning your hard drive has become a lot easier than in previous Windows versions.

Make Sure Windows Update Has Completed All Important Updates

A new preview build won’t install if important updates are pending. Go to Windows Update via Control Panel or PC Settings, as described above, and check for updates. Just to be sure, reboot once more after the last update was installed.

    every time I get a new preview build I have to take 4 hours to redo all of my system settings, for example, I have to disable one drive again, login preferences, etc.. can't you just save all of my settings and files and just install the new features, I don't know, but its kind of a pain, and I'm thinking of dumping windows insider altogether. hope you can do something.

    thank you

    Can you please update this article for build 10130? There is no "PC Settings" any more (just Settings) and there is no "Update and recovery" option either, so I'm unsure where to find the option to check for new builds?

    I have a similar problem to Bob. It downloads fine, does the first restart and then gets to 31% and down the bottom it states Applying PC settings 4%. Pretty sure its frozen (left it for 5-6 hours and it was still the same) but now this is my second attempt at installing (new download) and its frozen at the exact same part.
    Would it be better if i made a bootable install USB of Windows 10 and install it that way??
    Maybe i should download an earlier, working build of Windows 10??
    Help pls!

    I tried using the Windows Update to install 10 and it gets about 30% through the upgrade and I get an error. Says PTI misuse and then it reverts back to Windows 7. I ran the compatibility tool and it said the computer was good to go.

    Hi Tina, how long does the step "Checking for updates" (after selecting how I would like to keep my files) take? I lost all my patience when the setup.exe shows this screen for around 15 minutes. Appreciate a reply, thanks!

    • Tina

      Shouldn't take that long, but I've seen this happening. Usually rebooting helps, then sometimes it shows "checking for updates" while already downloading, so just let it do its thing and make sure your Internet connection is steady.

      My update went smoothly, but you're not the only one who's having issues with getting the new build.

      I'd seek help at the Microsoft TechNet Forum.

      Good luck!

    Question ,,If i install windows 10 and it fails could i do a simple factory reset to remove the update or will i have to create a recovory disc as i dont keep much on this computer ?

    • Tina
      March 15, 2015 at 1:19 pm

      What do you mean with "fails"?

      Windows 10 comes with almost the same recovery options as Windows 8, so it does support a reset or refresh of the OS.

      You can always do a factory reset if you preserve the recovery partition, if your computer has mechanism to launch a factory reset (boot into recovery; alternatively using boot media), and if you have a Windows product key for recovery (might be written to your BIOS).

      February 26, 2015 at 8:23 am

      You can switch to the Slow ring to not get new builds right away. As for not automatically installing new builds at all, I guess only a registry hack would work. Can't help you there, I'm afraid.

    @Tina How much size the direct update consume?

    • Tina
      January 28, 2015 at 3:59 pm

      The ISO is around 4GB. Once installed, Windows 10 takes up around 24GB (system and reserved). I'm not sure how much extra free space you need when you're upgrading from Windows 7/8 or from a previous build. I'd guess it's at least 4GB for the previous build.

    Could it be that your internet connection is slow? It took about half an hour for me over WiFi. Make sure you don't have other downloads running. Could also be that it got stuck. Have you tried rebooting?

      Not eligible for the latest build? Make sure all updates are installed via the Windows Update Control Panel (not the modern app). Reboot, check for updates again, and when they've all been applied, try again. Good luck!

    It would be great to have an article on how to do this from Windows 7.

    • Tina
      November 17, 2014 at 3:50 pm

      Don, it can be done from Windows 7, this article explains how to install Windows 10. Once the new Preview Build is available as an ISO, just download the new ISO instead of the original Build. Is that what you were looking for?

    • DonGateley
      November 17, 2014 at 7:17 pm

      Thanks, Tina. Do you know if the ISO allows for an over-install that will keep applications or a dual boot install? I've tried to install it from within a 32 bit Windows 7 Starter Edition to no avail. It basically just says "no."

      I need to benchmark it's audio performance on bare metal so the VM solution is a no go but I want to keep the existing installation if this proves to be a failed experiment.

    • Tina
      November 20, 2014 at 4:11 pm

      You should be able to upgrade your OS from within and keep your settings, personal files, and "most apps". Do make backups though and create recovery media in case you want to downgrade later. Better yet, prepare a system image.

      Did you download the 32-bit version to install from within Windows 7 Starter?

      You could also try to install a dual boot next to Windows 7, that's what I did.
