To me, being "enterprise" means shipping/supporting running enterprise functions on the OS. So things like network information services, databases, perhaps giving options of filesystems that can handle extremely large sizes, cluster support, added support from the vendor, etc.

Stuff that a typical desktop user probably won't run or use. Maybe they can if they really wanted to, but not the common use case.

>Is Windows not "enterprise"?

Funny you ask when Microsoft literally sells a version of Windows called "Windows Enterprise". https://www.microsoft.com/en-us/windowsforbusiness/compare

Find the differences between Windows 10 Home and Windows 10 Enterprise and that may help you understand what makes Rocky Linux also enterprise.
