TFS “Assign To” is showing too many users

Question

I am connected to a TFS server, and when I create a work item (Bug, Task, etc.), the \"Assign To\" shows WAY too many users. I cannot find a way to limit the users shown tha

Answer 1

See my answer here for 2012, it may be similar: Visual Studio - Don't display all domain users in "Assign To" field

The problem was that [TEAM FOUNDATION]\Valid Users included [TEAM FOUNDATION]\Team Foundation Administrators which included [BUILT IN]\Administrators

In the TFS Server Administration Console I selected Application Tier and clicked Group Membership. I then double-clicked on [TEAM FOUNDATION]\Team Foundation Administrators and removed [BUILT IN]\Administrators.

Now I only see my team and not all the SQL admins and engineers that were local admins on the server. All without any command line or addons.
