any software developed to be sold to consumers
Microsoft has very successful commercial software.
(Or "commercial off-the-shelf software", COTS) Software that is produced for sale. This contrasts with free software, which is produced for free distribution, meaning without charge and/or without restriction on further distribution.

Conversely, software that an individual distributes for free, but for which he accepts donations, would still be called free software.
