Windows desktop background: how to have system info displayed

Some Windows machines can be configured with a desktop background that will query the local system for its hardware configuration, OS, configuration, statistics, etc.

What program do you need to install to acquire this type of desktop background?

That appears to be SysInternals' BGInfo.

It's a stand-alone executable that you place in your StartUp directory. You can create a Windows scheduled task to refresh it at an interval you choose.

BGInfo basically writes a new desktop bitmap image every time it is executed.

You can pick and choose the data presented, its fonts, colors, etc.

Rainmeter is popular once you've skinned it to show system data.
