VM created from Windows 10 TP template stuck at region select page

I need use System Center Virtual Machine Manager 2012 R2 to create VM with different locale settings.

Step:

1. Create VM with Windows 10 TP ISO.
2. Use local machine account 'A'.
3. Do some manual configuration.
4. Create VM template with this VM.

Template setting:
answer file with region settings (UI language, region, keyboard).
The OS type I select is Windows 8.1 or 64 bit 8.1 since there is no Windows 10.
I set the user ‘A’ and it’s password in  admin password section.

Result:
When create VM from the template, it will stuck at select region page, and need manually do some settings then it could go to desktop.
When I use the same process to create Windows 8.1 VM template, the VM created from template will directly go to desktop.

Question:
It seems even I set locale related info in answer file, it’s doesn’t work for Windows 10 TP, how could I get the same result as Windows 8.1 template?
