Adding languages in Windows 10: Known issues

This topic captures known issues that affect language provisioning in Windows 10.

Adding Local Experience Packs (LXPs) in Windows 10 version 2004 and later versions: Known issue

When servicing a Windows image that contains LXPs with a cumulative monthly security update or public preview, the corresponding LXP ISO for that update needs to be downloaded and installed to the system image prior to launching OOBE. If this step is skipped, then the user may experience unexpected language fallback (e.g., see text in a language that they cannot understand) until they are able to update their LXP via the Microsoft Store. Note that LXPs cannot be updated via the Microsoft Store until OOBE is completed (i.e., device has reached the Desktop) and the device has established internet connectivity.

To find the correct LXP ISO for your associated monthly quality update, look for the abbreviation of your update in the LXP ISO filename (e.g., 9B). If a quality update doesn't have a corresponding LXP ISO, use the LXP ISO from the previous release. Entries in the table below are listed from newest to oldest.
