I see what your saying, Mine shows Windows 10 Pro Insider Preview for Product Name in Showkey. If I take the key shown as installed key and type it into the Check Product key option, it shows as Windows 10 Pre-release Professional Retail. I missed the pre-release part, must have got distracted by seeing the Retail part listed. Sorry for the confusion. The Retail listing surprised me as it was an upgrade from an OEM install.
