*Disclaimer: I am a developer not a sysadmin*

I have just installed Windows Server Essentials 2016 on a small office network and noticed that it has automatically created shares called `CertEnrol`, `Shared Folders`, `Users` and a few others.

It has also created a folder on each volume called `ServerFolders`.

What are these and am I safe to remove them?
 I haven't seen them before on other servers.

I don't really want the users to get confused by them and if they are important then I don't want to encourage them to poke around in there.
