Any difference between These Upgrades of OS?

When I got the update for my Windows 10 Pro 10240 build 10240, the update were mentioned as Wondows 10 Pro 1511 build 10586. But when the updates were downloaded and installed, I looked into system information which mentioned as Windows 10 Pro 10586 build 10586. Are these identical or any difference between the two? Why the letters 1511 not mentioned?

1511 is the version 10586 is the build. They are the same thing. If you type winver in start you should see both.



1511 is a new naming convention signifying 15 for the year and 11 for the month so if there was one in 6 months the version would be 1605.

Thanks for extending my knowledge.
