What's new for Windows 10, version 20H2 and Windows 10, version 2004 release notes
Windows 10, versions 20H2 and 2004 share a common core operating system and an identical set of system files. As a result, the release notes for Windows 10, version 20H2 and Windows 10, version 2004 will share an update history page. Each release page will contain a list of addressed issues for both 20H2 and 2004 versions. Note that the 20H2 version will always contain the fixes for 2004; however, 2004 will not contain the fixes for 20H2. The update history page will provide you with the build numbers for both 20H2 and 2004 versions so that it will be easier for support to assist you if you encounter issues.

Workaround |

Certain Japanese half-width Katakana and full-width Katakana characters that have a consonant mark aren’t interpreted as the same character. When you use the CompareStringEx() function with the NORM_IGNOREWIDTH flag to compare them, these characters are evaluated as different because of an issue in the sorting rule. This issue affects all the updates starting on October 29, 2020 for Windows 10, version 20H2. |
Updated 12/9/20:
Important If you have not installed KB4586853or later on the computer, setting an invalid value in this registry might prevent the computer from starting up. This workaround reverts the National Language Support (NLS) sorting rule to version 6.2, which is used in Windows 10, version 1909 and earlier. When sharing data between systems, consider applying the workaround consistently. If you use this workaround, conduct sufficient testing and evaluations to mitigate problems caused by different sorting rule versions on multiple systems. |

We are working on a resolution and will provide an update in an upcoming release. |
