Our office has three servers with WS2016 standard. We upgraded SBS 2011 a few years ago. Some things still exist from that time. I don't think the following security groups are related to the SBS installation, but I'm not sure. They have no members and are not members of other groups. We run a couple of SQL servers, but I don't think it's SQL 2005 either.
I'm pretty sure these can be deleted safely, but I'm not very familiar with SQL, so I wanted to be sure. The server starting with WIN was a failed installation and no longer exists.
