When we released Windows 10, version 1803, we introduced Local Experience Packs (LXPs), which are modern language packs delivered through the Microsoft Store or Microsoft Store for Business. The biggest advantage to LXPs is that we no longer have to wait for feature update releases to deliver improved translations to you. Instead, translation improvements can be delivered via LXPs as a Microsoft Store application update.
Not only can language packs be updated based on user feedback, allowing new versions to be released and applied to all PCs via the Microsoft Store application update process, we have also made it easier for users to provide feedback on Windows display strings by going to the Language Community tab of the Feedback Hub.
With the introduction of LXPs, we have started to retire legacy language packs (lp.cab). Beginning with Windows 10, version 1809, we have retired legacy language packs (lp.cab) for all Language Interface Packs (LIP).
After the OOBE, if the device is online and connected to the Microsoft Store or Microsoft Store for Business, Windows 10 will automatically bring in the appropriate LXP for the user so that the device always has the latest translations. If the device is in a corporate environment where Microsoft Store access is blocked, the user will not receive translation improvements. The device will only have the translations that were shipped with the corresponding OS release.
The information above is designed for OEMs or IT professionals. If you are an end user, you can install and set a display language by either going to the Settings and selecting Time & Language > Region & language or by visiting the Microsoft Store. For more information, see Get Windows to speak your language. We will ensure that you get the appropriate LXP and have up-to-date translations on your device.
