Modify the Windows XP System Properties logo The Windows XP System Properties logo is often changed by
computer manufacturers. Hardware vendors use this general system
information dialog to brand your computer with their own logo and
support contact information.
In this tip you can learn how you can insert your own logo in the
system properties dialog and complete it with your own contact
information.
To invoke the system properties dialog, click the Start button,
right-click "My Computer" and select "Properties".
This will open up your general system information dialog. On our
Fujitsu-Siemens Amilo Pro laptop, the Windows XP System Properties logo
looks like this :

If you want to put your own graphic in there, you should create
your image in a .bmp graphic file. It's also a good idea to create this
bitmap image with the same background shade of gray (RGB: 192, 192, 192)
used in the Properties dialog. Otherwise, you risk letting Windows make
its own judgments regarding color contrast and background shading.
The next thing to consider is the image size. The system
properties dialog only offers enough real estate for an image of about
180 (wide) x120 (high) pixels. Make sure that you can fit your logo in
this area.
Once you have created your logo and saved it as a .bmp file, copy
it over to the system32 subfolder of your Windows system folder. If you
don't know where your system folder is :
- Click the Start button and select "Run"
- In the "open" field, enter "cmd" (without the quotes) and
click ok
- Windows will open up a dos command window
- In the command window, type "set system" (without the
quotes)
- Look for the line that contains "SystemRoot", this is where
your system directory is (generally, the Windows XP system folder is
c:\windows)
Now that you know where your system folder is, copy your logo
image file over to the system32 subfolder of your system folder. Then
rename your logo image file to oemlogo.bmp
Additionally you can create a new file in this same folder and
name the new file oeminfo.ini
In this file you can enter your contact information like in the
example below :
[General]
Manufacturer=Windows Help Central
Model=ShowCase
[Support Information]
Line1=" "
Line2=" For support, sales, upgrades or questions:"
Line3=""
Line4=" Some text to demonstrate the XP System Properties logo"

Line9=" +1 (888) 888-889 (fax)"
Line10=""
Line11=""
Line12=" http://www.windows-help-central.com/"
Save and close the file and you are ready. From now on, if someone
opens up the system properties dialog, your own Windows XP System
Properties logo is in there.

And if someone clicks the "Support Information" button :
