By default, the General tab of the 'System' information window contains information on the systems Windows version, processor, memory, registered user and registration identity.

You can access this by right-clicking > properties on My Computer, by double-clicking 'System' in the Control Panel, or by press the Windows + BREAK keys on your keyboard.

 The standard window looks like:

 

Optional items may be displayed these include the manufacturer and model, a small picture, and a button leading to a separate page for tech support information. This is typically displayed in OEM systems with a company branding logo and company information.

The information on this window is not held in the system registry so this process is relatively safe. All displayed data is stored in an '.INI' file which can be created and manipulated with any Plain text editor. e.g. Notepad

The INI file can be made up of two sections:

Section 1

Labeled [General] is made up of these 2 entries

Manufacturer=<text>
Model=<text>  

Section 2

Labeled [Support Information], is optional, when present adds a 'Support Information' button linking to the included support Info.

This section is made up of these entries

Line1=<some text>
Line2=<more text>
Line3=<more text>

The limit on the number and length of lines is limited only by the 64 KB general limit on .INI files.

Once this file is created it will need to be saved as OEMINFO.INI and needs to be saved in %systemroot%\system folder (for Windows 98/ME computers) or in %systemroot%\system32 folder (for W2K/XP/2003 computers), where %systemroot% is the path to your windows installation.

An example OEMINFO.INI file contains:

[General]
Manufacturer=Technology Enigma
Model=www.techenigma.com

[Support Information]
Line1=Visit us at
Line2=
Line3=http://www.techenigma.com
Line4=
Line5=Tech News, Reviews and how-to's + more

Custom Image:

A custom image can also be displayed on the System Information window. The image must be a 256-colour-Windows bitmap (.BMP) file.

An example custom image:

 

Microsoft state that the size should be 96 pixels x 96 pixels when using small fonts in Display Property settings, or 120 square with large fonts.

Once this image has been created it will need to be saved as OEMLOGO.BMP and needs to be saved in %systemroot%\system folder (for Windows 98/ME computers) or in %systemroot%\system32 folder (for W2K/XP/2003 computers), where %systemroot% is the path to your windows installation.

No other entry in the .INI file is required, but the INI must exist and have a populated [General] section for the bitmap to be visible.

No reboot is necessary in order for the mod to take effect. Press the windows + BREAK keys to see the changes once these files are in place.

The outcome:
