Windows 10 build 20231.1000 is the sixteenth Insider Preview build of Iron, the 21H1 development semester of Windows as a service. This build was released to Windows Insiders in the Dev Channel on 7 October 2020.

New features and changes[edit | edit source]

These features are only available to a small group of Insiders at first, meaning that not everyone will see them right out of the box, and will roll out to the rest of Insiders soon.

A new page was added to the OOBE to help new users to plan how to customize their devices basing on their intended usage.
Enterprise users can now modify file associations on a per-user or per-device basis.
The "Meet Now" feature introduced in build 20221 is now rolling out to all Insiders in the Dev Channel. However, it's still not available on Enterprise SKUs or Azure Active Directory (AAD) user accounts.
Graphics card information is now displayed in Settings → System → About.
The change to enable moving the text cursor via gestures on the touch keyboard introduced in build 20206 is now rolling out to all Insiders.

Findings[edit | edit source]

Windows Spotlight desktop background[edit | edit source]

Another hidden change is the ability to use Windows Spotlight images, which appear on the lock screen, as desktop backgrounds. To enable this feature, download the Vibranium Velocity (Vive) tool, extract the contents from the ZIP file, launch the executable from an elevated Command Prompt window, type the following command, and restart: vivetool addconfig 26008405 2. After restart, you should see a "Spotlight collection" option in Settings > Personalization > Background.

Bugs[edit | edit source]

The update process to this build has a chance of hanging for extended periods of time.
Live preview doesn't work for pinned site tabs.
Some Office applications may either crash or go missing if you update to this build.
There's a chance of randomly encountering a BSOD with the error code KMODE_EXCEPTION when using certain virtualization technologies.
There's a chance of randomly encountering a DPC_WATCHDOG_VIOLATION BSOD.
When some Insiders updated to this build, they encountered a Compatibility Assistant notification that said “Microsoft Office is no longer available”. Despite the warning, the installed apps from the suite were still available and functional.
Selecting an IME candidate or hardware keyboard text prediction candidate may insert the candidate adjacent to the one selected.
In some PCs, the taskbar is obscuring the Power button on the Start menu blocking the access to its options. To workaround this issue, use the options from the User menu (⊞ Win+X).
The gesture controls for the touch keyboard might still not be working on some machines.
There is a chance of the new OOBE showing a keyboard error before switching to some pages. However, it can be safely skipped.
The Spotlight collection feature is non-functional since the endpoint to gather wallpapers is not working.
