The MCT-IN (India) is exclusive to OEMs, such as Acer with recovery media for Gateway NV57H58u (2011) https://archive.org/details/GatewayNV57H58uRecoveryMedia. Some OEMs bundle and register MCTs from more than one vanilla image in one OEM image. However, this is also mentioned in a post on the official Windows Experience Blog.

It's possible to add all regional themes and make them work the same way as vanilla ones (pre-made configuration files included): https://winclassic.net/thread/2752/windows-change-accepted-regional-wallpapers
