This article applies only to Windows operating systems.
If you dont know how to take System Properties tab, do this, Right click the My Computer icon on the desktop, select Properties. By default the General tab will be shown. This is the System Properties.
System Properties can also be accessed from the Control Panel.

Step 1.
Create an bitmap image of width 180 px and height 115 px. You can use any image editor to do this. The Paint program in windows works fine. If you want to use any other file, first convert the image to bitmap format. If you have a large bitmap file than 180 px and 115 px, dont worry, you can use your file but only 180 px x 115 px from the center of the image will be shown.
Now rename your bitmap file to “oemlogo.bmp”, without quotes, and store it in your System folder.
Please note that in Windows 98 the System folder is in x:\windows\system
and in windows 2000
the System folder is in x:\winnt\system32
Step 2.
Create a file named “oeminfo.ini” , without quotes, in your System folder.
Open this file in a text editor a write this
[General] Manufacturer=Write some thing here Model=Write Something here Owned= [Support Information] Line1= This info will be showed Line2= when you click the Line3= Support Information button Line4= This is another line Line5= This is yet another line
Please note that the oeminfo.ini file should contain these sections
[General]
Manufacturer=
Model=
Owned=
[Support Information]
Line1=
Example:
[General]
Manufacturer= Kiran Paul V.J.
Model=AMD
Owned=OEM generated file.
[Support Information]
Line1= This computer is owned by..
Line2=Maintained by : ***********
Line3=Use this computer at your own risk
Line4=
Line5=Contact info : some...@somewhere.com
Line6=Please dont spam
Line7=http://www.einternals.com
Its done, now open the System Properties to view the changes.
