Hi Peter,
Thanks for the update. But it seemed the problem was more than problem fix but a feature request for keyboard usage in VMware for windows when RDP.
Since then, please vote on the items with similar request in the UserVoice forum, where the product team will regularly visit.

Thanks for your understanding and look forward to assisting in the future if any problem related to RDS.
Hope this helps and please help to accept as Answer if the response is useful.
Thanks,
Jenny
