Group Policy is an extremely flexible and complicated tool. One question I am asked quite a bit is, “Can you give me a list of settings I need to enable?” The short answer is No, Microsoft has already enabled the vast majority of things that should be enabled. And while Microsoft’s guidance may change over time (see Offline Files as an example of this), most settings stay the same. There is one setting, however, that is not enabled by default. If you are going to use Group Policy and want to make your troubleshooting life easier, you will want to enable it.
