The service helps to automate the process of keeping Windows, Edge and Office software up to date and aims to eliminate the risk of bugs and security issues. It is supposed to ensure the latest patches and updates are installed and it simplifies the process of rolling back changes should a problematic update be rolled out.
Volish engineers use the Windows Update for Business client policies and deployment service tools on your behalf. The service creates testing rings and monitors rollouts-pausing and even rolling back changes where possible.
Vole is only making the software available to customers with Windows Enterprise E3 and E5 licenses so it is probably not for the likes of you.
Some of you will probably be relieved about this.
