Windows 10 Build 20231 released to the Dev channel

Microsoft has released a new Insider Preview build of Windows 10 to Insiders in the Dev channel. Windows 10 Build 20231 includes a redesigned OOBE page with checkboxes, and new deployment features.

What’s new in Build 20231

Improving relevancy of initial device setup

Based on feedback, we’re exploring adding a page to Windows setup (OOBE) to help better understand how you plan to use your device and aid in customizing your device given your intended usage.

This is the initial wave of work for this feature, and Insiders may notice different options presented in OOBE depending on what they select, however at this time Insiders will not notice any other configuration differences after exiting OOBE. We look forward to sharing future improvements in this space.

This feature is rolling out to a subset of Insiders in the Dev Channel at first, to help us quickly identify issues that may impact performance and reliability. Rest assured they will be gradually rolled out to everyone in the Dev Channel. NOTE: You will see this feature if you choose to reset your PC and when you do a clean install of Windows. You can find the ISO for Build 20231 here on our download page later today.

Better Management Options for App Default File Associations 

Enterprise customers can now modify file associations on a per-user or per-device basis. This change will apply to existing users as well as users with new deployments. This means that IT admins can set which apps will automatically open various file types or links. For example, this makes it easy to set Microsoft Edge as your organization’s default browser, or always open PDFs in your organization’s preferred app. Leveraging this group policy for the default browser and common file types means that your organization’s end users will not have to decide on these defaults themselves.

Deployment/Testing Steps:

  1. Generate Default Application Associations XML file by following this page.
  2. Manually modify the XML by adding 2 new properties:
  3. Add Version=”1″ to the DefaultAssociations tag.
  4. Add Suggested=”True” to any Association tag.
  5. Enable the group policy to set the default file associations by following this doc.
  6. Reboot or log in as the user.

Please note: If your device does not have this feature enabled, the policy will fall back to the default logic and will not respect the “Version” and “Suggested” fields of the policy.

This feature is rolling out to a subset of Insiders in the Dev Channel at first, to help us quickly identify issues that may impact performance and reliability. Rest assured they will be gradually rolled out to everyone in the Dev Channel.

Updates for developers

The Windows SDK is now flighting continuously with the Dev Channel. Whenever a new OS build is flighted to the Dev Channel, the corresponding SDK will also be flighted. You can always install the latest Insider SDK from aka.ms/InsiderSDK. SDK flights will be archived in Flight Hub along with OS flights.

Known issues

  • If you were one of the Insiders repeatedly entering a temp profile with the previous flight, please refer to the following forum post to get your profile back into a good state. If you were not impacted, this issue will not impact you in today’s flight.
  • We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
  • We’re working on a fix to enable live preview for pinned site tabs.
  • We’re working on enabling the new taskbar experience for existing pinned sites. In the meantime, you can unpin the site from the taskbar, remove it from the edge://apps page, and then re-pin the site.
  • We’re working on a fix for an issue where some Office applications crashing or missing after updating to a new build.
  • We’re working on a fix for an issue causing some devices experiencing a KMODE_EXCEPTION bugcheck when using certain virtualization technologies.
  • We’re working on a fix where some devices are experiencing a DPC_WATCHDOG_VIOLATION bugcheck.
  • We’re working on a fix for an issue where after taking this build some users receive a Compatibility Assistant notification that “Microsoft Office is no longer available”. Despite the notification, Office should still be there and working fine.
  • We are working on a fix for an issue where selecting an IME candidate or hardware keyboard text prediction candidate may insert the candidate adjacent to the one selected.
  • We’re investigating an issue reported by some Insiders wherein the taskbar is obscuring the Power button in the Start menu. If this is happening on your PC, you may need to use the Windows key plus X menu to shutdown for the time being.

The Dev Channel, formerly known as the Fast Ring, reflects the latest changes made to the Windows code base. It is a work-in-progress, so the changes you see in Dev Channel releases may not appear in the upcoming feature update. So we can expect to see some features which will never appear in stable Windows 10 versions on Desktop.
Also, it is possible that Microsoft will bring some Windows 10X features to Windows 10 on Desktop. Microsoft is about to add some of Windows 10X's features to get the best of two Windows branches. The company may also replace some of the Desktop feature updates with Windows 10X releases.

If you have configured your device to receive updates from the Dev Channel/Fast Ring ring, open Settings - > Update & recovery and click on the Check for Updates button on the right. This will install the latest available Insider Preview of Windows 10.
