As this MS KB article states:
A hidden share is identified by a dollar sign ($) at the end of the
share name. Hidden shares are not listed when you look through the
shares on a computer or use the net view command.
By default, Windows can enable the following hidden administrative
- Root partitions or volumes
- The system root folder
- The FAX$ share
- The IPC$ share
- The PRINT$ share
Root partitions and volumes are shared as the drive letter name
appended with the $ sign. For example, drive letters C and D are
shared as C$ and D$.
The system root folder (%SYSTEMROOT%) is shared as ADMIN$. This is
your Windows folder, and the administrative share provides
administrators easy access to the system root folder hierarchy over
The FAX$ share is used by fax clients to send a fax. This shared
folder caches files and accesses cover pages that are stored on a file
The IPC$ share is used with temporary connections between clients and
servers by using named pipes for communication among network programs.
It is primarily used for to remotely administer network servers.
The PRINT$ share is used to remotely administer printers.
Hidden administrative shares that are created by the computer (such as
ADMIN$ and C$) can be deleted, but the computer re-creates them after
you stop and restart the Server service or restart your computer.
Hidden shares that are created by users can be deleted, and they are
not re-created after you restart your computer.
Since it's a work PC and your network admin didn't disable the shares, I see no need for you to do so either.
