BgInfo is a free tool from Microsoft that displays system information on the desktop background such as the computer name, IP address, and operating system version. It can be customized with different fields, fonts, and background colors. BgInfo runs at startup or login to always show relevant details without needing to open diagnostic windows. The tool is useful for system imaging and deployment by populating the computer name on cloned systems.

I usually rename to OLD.LocalizedString and create a new string but some people
simply modify the value... it's up to you.
Edit it reads:
Name = LocalizedString Type = REG_EXPAND_SZ Data = %COMPUTERNAME%
You can also display user name data value = %USERNAME% on %COMPUTERNAME%
It's valuable in disk imaging as when you deploy and give the computer name
you'll always have it. You may need to change permissions on the key. Right click
on the key and select permissions.
You are looking for Microsoft's Sysinternals BgInfo. It is very customizable. Not to mention
it comes straight from Microsoft for free.
How many times have you walked up to a system in your office and needed to click through
several diagnostic windows to remind yourself of important aspects of its configuration, such
as its name, IP address, or operating system version? If you manage multiple computers
you probably need BGInfo. It automatically displays relevant information about a Windows
computer on the desktop's background, such as the computer name, IP address, service
pack version, and more. You can edit any field as well as the font and background colors,
and can place it in your startup folder so that it runs every boot, or even configure it to
display as the background for the logon screen.
