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 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.

Note:  When enrolling a new device into the program, the default ring selection is Fast.  Please verify below which ring fits your preferences and set on your device accordingly.

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 analyzed by our Engineering teams. These builds are serviced using the same tools and processes as our production builds, including our weekly security fixes, and address key issues that prevent many Windows Insiders from being able to use Fast ring builds on a daily basis. Note: Slow ring builds are still from the Development Branch and could have issues that might be addressed in a future flight. Learn how to Install.

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 to 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. Enrollment 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 Updates & Security, select Windows Insider Program. Under Choose Your Level, select between the following rings: Fast, Slow or Release Preview.

Working with updates

After registering in the Windows Insider Program and installing your first Windows 10 Insider Preview build, you will begin to receive updates to the device(s) 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, is 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 1 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 you may find useful as you participate in the program. 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, click “winver - run command.”

How to verify which flight ring I have selected

Open Settings, select Update & Security, select Windows Insider Program. The flight ring you have selected will appear under “Pick your Insider settings”.

How do I check which Microsoft Account (MSA) or Azure Active Directory (AAD) account I am using for getting builds?

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

How do I verify 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 Program, 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 your device is left turned on and signed in during the off-hours so the install process can complete.

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 PC registered for receiving builds?

Click here to sign in with your MSA or AAD account. You will land on the page “Already a member,” if your MSA or AAD account is registered with the Windows Insider Program.

Have you selected a ring?

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

Have you recently done a roll-back?

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

Did you do a clean install?

After a clean-install 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 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 alternate 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 on Twitter. If important functionality is unusable, you may want to reinstall your current OS version. Prior to doing any reinstall or rollback, ensure 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 Reinstall

You will have several options to choose from, including an operating system-only reinstall 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 afterward, 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 program.

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 opt a device out of the Insider program, go to Settings > Update & Security > Windows insider Program and turn on the Stop getting preview builds setting.

If the device is currently running a public release of Windows, opting out will happen immediately. Your device will require a reboot to complete the process.

If the device is currently running a prerelease version of Windows, it will continue getting updates until the next public release is installed. At that time we will take care of the opt out for you, without any action on your part (please note that depending on development timelines this could take some time.) We do this to ensure your device does not get stranded on an unsupported version of Windows that may contain security vulnerabilities.

If you do not want to wait for the next public release to opt out of Insider builds, you can clean install Windows immediately. 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.
