This simple application can increase the productivity and reduce the mistakes made by IT technicians and system administrators when managing large server clusters or companies with thousands of end-users.
It reduces the amount of time spent looking for basic settings of workstations, laptops and servers aspects such as its name, IP address, operating system version, MAC address, up-time or even the current Teamviewer ID, by adding it as text to the current desktop’s background image or logon screen, and its fully customizable and does not consume system resources.

For example in my virtual Microsoft lab I use it to see all the names and IPs.
