Immigrating to Portugal friends will soon be able to welcome the Portuguese version of Cortana. According to media reports, Microsoft is already internally testing the Portuguese version of Cortana, although the specific release date is not yet clear. We hope the wait will not be too long.
Currently, Cortana has completed its cross-platform launch, but it is not available in every region worldwide. At present, the U.S. and Chinese versions of Cortana are developing the fastest. However, for example, Brazil, which is the third-largest WindowsPhone market, has not yet welcomed Cortana, though it is imminent.
A leaked document from January 2015 showed that Microsoft was developing Russian, Arabic, and Indian versions of Cortana, which would be launched along with Windows10, but as of now, they have not been officially released. Perhaps we need to wait for the next Win10 major update, Redstone, which is expected to arrive this summer.
