Windows 10/8/7: How To Fix Group Dependency Failed To Start Error

How to resolve "The dependency service or group failed to start".

Issues addressed in this tutorial:
dependency service or group failed to start windows 7
dependency service or group failed to start windows 10
dependency service or group failed to start windows 8

A pretty well-known Windows issue, pretty much because of the sheer number of people who were and still continue to be affected by it, is one where the affected user’s access to the internet becomes entirely non-existent and a message that reads “The dependency service or group failed to start” is displayed in their Network & Sharing Center. This issue first affected Windows 7 users but, since then, has also been found on other versions of the Windows Operating System.

Users affected by this issue become incapable of connecting to the internet on any and all networks regardless of whether they try to connect wirelessly or via an Ethernet cable. Any attempts to troubleshoot this problem from the Network & Sharing Center result in failure and yet another message which reads “The Diagnostic Policy Service is not running”.

This tutorial will apply for computers, laptops, desktops, and tablets running the Windows 10, Windows 8/8.1, Windows 7 operating systems. Works for all major computer manufactures (Dell, HP, Acer, Asus, Toshiba, Lenovo, Samsung).
