Hi Moshe,
Please try the DISM command line to add basic typing capability.
For example, to add the (Chinese language) basic typing, run this command from Command Prompt admin:
Dism /Online /add-capability /capabilityname:"Language.Basic~~~zh-CN~0.0.1.0"
Restart Windows.
(If you receive any errors, please post them here.)
You can check out the list of language codes from the following link:
