Working with rings

Definition of rings

The options for the frequency of Windows 10 Insider Preview builds are called "rings". Each ring presents a different level of stability and will be delivered on a different build cadence.

Rings are used to evaluate the quality of our software as it is released to progressively larger audiences. If the build passes all required automated testing in the lab, we will flight (release a build) with a new feature update, application etc. to the first, most frequent, ring. The build will continue to be evaluated against a set of criteria to ensure that it is ready to progress to the next ring. To get builds to Insiders faster, we changed the ordering of how we promote builds between rings, the ring progression criteria and added a new ring.

Fast Ring

The benefit of being in the Fast Ring is that you will be among the first to use and provide feedback on new and improved features. If you have devices in the Fast Ring, you should be prepared for more issues that might block key activities or might require significant workarounds. Because we are also validating a build on a smaller set of devices before releasing, there is also a chance that some features might fail in some device configurations. If significantly blocked, report the issue to us in the Feedback Hub app or the Windows Insider forums and be ready to reinstall Windows using the Media Creation Tool, see instructions at Download Windows 10.

Slow Ring

The benefit of being in the Slow Ring is that you'll still receive new updates and features on the Development Branch, but the builds will be more stable. Builds are sent to the Slow Ring after feedback has been received from Insiders on the Fast Ring and analysed by our Engineering teams. Slow Ring builds include updates to fix key issues that prevent many Windows Insiders from being able to use the build daily. These builds are still from the Development Branch and could have issues that might be addressed in a future flight.

Release Preview Ring

If you want to be on the current public release of Windows 10 but still get early access to updates, applications and drivers without taking the risk of moving to the Development Branch, the Release Preview Ring is your best option. The Release Preview Ring is only visible when your Windows build version is the same as the current Production Branch. The easiest way to go between the Development Branch and the current Production Branch is to reinstall Windows using the Media Creation Tool, see instructions at Download Windows 10.

Skip Ahead

This is a unique version of the Fast Ring that allows Insiders to "skip ahead" to Windows 10 Insider Preview builds in the next release while we are finishing up a current release. Enrolment in Skip Ahead is offered for a limited time to a small subset of Insiders.

Switching between rings

Changing rings is a simple process. Launch Settings, select Update & security, then select Windows Insider Programme. Under Choose Your Level, select between the following rings: Fast, Slow or Release Preview.

Working with updates

After registering in the Windows Insider Programme and installing your first Windows 10 Insider Preview build1, you will begin to receive updates to the device(s) that you have enrolled. During the development process, the build number will change with each update. There are two different types of builds being delivered to your device(s):

Major builds

When a major build is released, it will include any combination of new features, updates to existing features, bug fixes, application changes or other changes. For a major build, you will see the build number increment by one or more. Build numbers may or may not be consecutive based upon passing internal ring promotion criteria. For example, 14361 -> 14365.

Minor/servicing builds

Also known as "servicing" or "cumulative" updates, these builds represent a smaller set of changes to a currently released major build. Servicing builds often include bug fixes, minor operating system updates or other smaller changes as needed. For example, 14361 -> 14361.1002 -> 14361.1003.

What to expect in each ring

While there is no set requirement for how build numbers are delivered to each ring, you will in general find the following to be true:

Fast Ring: major build releases, very few servicing builds.

Slow Ring: major build with minor build fixes attached.

Release Preview Ring: major build change at a release milestone and then a continued series of servicing builds until the next release milestone is reached.

Find information about your PC

Below is a set of quick references for key information that you may find useful as you participate in the programme. This information will also be helpful when submitting feedback for build issues or feature suggestions, as well as reaching out for assistance.

How to find the build number

Go to Start, type winver and click "winver - run command".

How to verify which flight ring I have selected

Open Settings, select Update & security, select Windows Insider Programme and view the Choose your Insider level drop-down.

How do I check which Microsoft Account (MSA) or Azure Active Directory (AAD) I am using to get builds?

Open Settings, select Update & security, select Windows Insider Programme and view the Windows Insider account information as displayed.

How do I verify that my copy of Windows 10 is activated?

Open Settings, select Update & security and select Activation. View the data as displayed.

Not receiving updates

While participating in the Windows Insider Programme, you may find that your PC is not updating to the latest update as expected. This is rare; however, there are a few key items to review should you end up in this state.

Perform a manual check for updates

Open Settings, open Update & security and review available updates or select Check for updates. If you have set Active Hours, ensure that your device is left turned on and signed in during the off-hours so the installation process can be completed

Is your copy of Windows activated?

Open Settings, select Update & security and select Activation. View the data as displayed.

Is the MSA or AAD account connected to your device registered for receiving builds?

Click here to sign in with your MSA or AAD. You will land on the page "Already a member" if your MSA or AAD is registered with the Windows Insider Programme.

Have you selected a ring?

Open Settings, select Update & security, select Windows Insider Programme and view the Choose your Insider level drop-down.

Have you recently done a rollback?

Check your Windows Insider Preview settings, including ring selection, Microsoft Account and branch selection.

Did you do a clean installation?

After a clean installation and initial setup of a Microsoft Account, even one that has been used previously for receiving Insider builds, the appropriate targeting needs to take place for your PC. This background process is known as Compatibility Checker and will run during idle time on your PC. This may take up to 24 hours. Please leave your PC turned on to ensure that this occurs in timely manner.

Are there any known issues for your current build?

There may be an issue with a build that could lead to issues with updates being received. Please check the most recent Windows Insider Blog Post or reach out to us @WindowsInsider.

Recovering a PC

If you are in a situation where you are unable to use your PC as expected, we want you to know how to recover your PC to a good state.

Assess the impact

  • What is the impact of the issue? Single app? Minor functionality?
  • Can you continue using your device or is key functionality not working?
  • Are you able to work around the issue? Would an alternative app suffice?
  • Is a newer build available that may have a fix for any known bugs being faced?

Troubleshoot & discover

Troubleshoot the issue. There may be a workaround available. Reach out to us via the Windows Insider Forums or @WindowsInsider. If key functionality is unusable, you may want to reinstall your current OS version. Prior to doing any reinstallation or rollback, ensure that you have backed up important files. While it is rare to lose data during this process, it is best to back up key data.

OS Reinstallation

You will have several options to choose from, including an operating system-only reinstallation or a clean wipe of your device: go to Settings > Update & security > Recovery and click Get Started under Reset this PC. Follow the on-screen directions to refresh or clean-install the OS.

Roll back to Prior Build

If your PC was working as expected on the prior build and you'd like to roll back without losing any data, you may try this option: go to Settings > Update & security > Recovery and select Get Started under Go Back to an Earlier Build.

Note: After installing an update to your PC, you will have seven (7) days to roll back if necessary. If required afterwards, you will need to take a future update or you may clean-install an older build via bootable media.

Clean-install Insider build via bootable media

One of the questions that comes up from time to time is how to create a bootable USB with a Windows Installation (from an ISO file). Having this can be helpful in various scenarios, from recovering a machine from a bad build, to bypassing various types of bugs, or even joining a new PC into the Windows Insider Programme.

Should you want (or need) to create a bootable USB drive from a Windows Insider ISO file, please see these directions.

Stop receiving Insider builds

To stop receiving new builds on your PC, go to Settings > Update & security > Windows Insider Programme, select Stop Insider Preview Builds and follow the additional on-screen prompts.

Recover your device

We recommend that you stop getting builds when your device is on a Production Build so that you do not need to recover your device. Production builds are stable, receive servicing updates and will allow you to stay up to date, and you will not lose any of the data on your device. If you unenrol while your device is running an Insider build, your device will remain on a build that will not receive future servicing updates, will have an expiry date set and may contain security vulnerabilities.

To find out the current Production Build number, check the Windows Insider Blog.

To find the build number on your PC, go to Start, type winver, click "winver - run command".

If you choose to stop receiving Windows Insider builds during a development cycle and need to recover your PC to a current Production Build, you will need to install an earlier version of Windows using the Media Creation Tool. Please see instructions at Download Windows 10 or choose from the following, depending on which previous version you are recovering to: Windows 7 Recovery image, Windows 8 Recovery image or Windows 10 Recovery image.

Support resources

Even though Insiders are self-sufficient people, the Microsoft team is ready to help you use Windows 10 Insider Preview builds. Along with the information provided in the How to section, the following options are available for support.

Windows Insider Blog

With each new build, we publish a Windows Blog post that outlines key feature changes as well as known issues that Insiders may encounter while using the build. Review the blog to stay up to date with news and information. Read the Windows Insider Blog today.
