Build 10547 - Hiper-V and Interface language, how can I change the language?

[Windows Central Question]

Build 10547 - Hiper-V and Interface language

1 - Lost Hyper-v configuration and virtual machines.

2- Cannot change the interface language from Italian to English.

Any solution for these issues or revert to previous version?

Many thanks.
