The term "product key" in your search phrase points to the software’s copy protection system. In 1995, the internet was in its infancy, and software was primarily distributed on CD-ROM or floppy disks. Publishers like Hot Virtual Keyboard used 25-character alphanumeric product keys to prevent piracy.

A typical HVK95 product key looked similar to Windows 95’s own key format (e.g., 12345-OEM-678910-12345). Users had to enter this key during installation; otherwise, the software would run in a limited "trial mode" or not at all.

The word "hot" appended at the end of the phrase is likely a search operator or tag used on keygen sites, crack forums, or abandonware databases to indicate that the provided key is "hot" (i.e., freshly generated, working, or not blacklisted).
