From what has been discussed so far, Windows 10 has incorporated new stuff in almost every aspect. From Windows Update to the Windows Insider Program, these are just a few of the new things introduced with Windows 10. Similarly, the three servicing channel options, such as CB, CBB, and LTSB, represent a new approach in terms of how updates are managed in Windows 10.
CB is now known as Semi-Annual Channel (Targeted) and presents the latest version of Windows 10. Semi-Annual Channel (Targeted) means the updates are ready for download for most home users. This servicing channel enables your Windows 10 device to receive all of the updates and the latest upgrade from the Microsoft Windows Update server within a few days of their release.
