Unable to create local users in Chinese, Japanese and Korean during device setup
When setting up a new Windows device using the Out of Box Experience (OOBE), you might be unable to create a local user when using Input Method Editor (IME). This issue might affect you if you are using the IME for Chinese, Japanese, or Korean languages.

Note This issue does not affect using a Microsoft Account during OOBE.

Affected platforms:
  • Client: Windows 10, version 1909; Windows 10, version 1903; Windows 10, version 1809; Windows 10 Enterprise LTSC 2019; Windows 10, version 1803; Windows 10, version 1709
  • Server: Windows Server, version 1909; Windows Server, version 1903; Windows Server, version 1809; Windows Server 2019; Windows Server, version 1803; Windows Server, version 1709
Workaround: To mitigate this issue, set the keyboard language to English during user creation or use a Microsoft Account to complete OOBE. You can set the keyboard language back to your preferred language after user creation. Once the OOBE is done and you are at the desktop, you can rename the current user using these instructions. If you prefer to create a new local user, see KB4026923.

Next steps: We are working on a resolution and will provide an update in an upcoming release.
