- Enables Text-To-Speech (TTS) functionality to support new Japanese Era characters.

- Fixes a problem that may cause a touch screen to stop working after restart.
- Allows existing devices that are managed by Configuration Manager to be enrolled in Microsoft Intune using Co-management without any user interaction. It does not require an active user to be logged in, and there are no Multi Factor Authentication (MFA) prompts. This update also allows the Co-managed mobile device management (MDM) enrollment to use the device credential it received when the device is enabled to join Hybrid Azure Active Directory (AADJ).
- Addresses an issue that prevents BitLocker from encrypting a removeable drive when there is no connectivity to store the recovery key in Active Directory or Azure Active Directory.
- Addresses a gradual memory leak in LSASS.exe on systems that have cached logon enabled. This issue mainly affects servers that process many interactive logon requests, such as web servers.

This key allows you to create a new RUP for an upgraded OS and prevents the loss of a custom Start menu. The RUP must be stored locally, and you must restart the device to enable the feature.
