Troublesome why or how?

They are part of the infrastructure of Windows NT and used in
Windows-to-Windows comms, domains, management etc. They've been there
ever since NT first appeared; I deployed NT 3.1 in production, the
first ever release.

Leave them alone! If you remove them, yes, things will break.

They're only available to administrators, and your normal login
shouldn't be one, meaning that they should be inaccessible anyway.

There are a number of conventions in Windows just as there are in Unix.

In Unix, for example, due to an intentional code shortcut -- basically
a bug -- very early on, files whose names began with a dot were
invisible.

This proved both useful and problematic but it's remained and now it's
permanent.

Similarly, in Windows, a share whose name ends in a dollar sign won't be listed.

They are also meant to be admin-only accessible.

Linux does not respect this and shows them. The same as Linux shows
hidden files on Windows filesystems, lets you delete R/O files on an
NTFS, and so on. It's useful.
