Add, Remove or Change OEM Information Manually or with Portable OEM Injector

If you have purchased a branded Notebook or PC, you must have seen a logo, Manufacturer and Model name in Windows System properties. This are the OEM information that every manufacturar attaches in a PC/Laptop they build. If you are a tech savvy user and don’t like such information to be displayed in your computer or if you are a computer assembler and build custom PC, you must have liked to change, remove or add custom OEM information. OEM information can be added, removed or changed by doing some alterations in Windows Registry. If you don’t like to play around Windows registry, you may use a portable software called OEM Injector from the same developer as Encryption Apparatus.
Manual Way to Change OEM Information
Windows 98/ME/W2K/XP/2003 computers
Create a logo
Create a logo in BMP format with 256 colors. It’s size should be 96 pixels square when using small fonts in Display Property settings, or 120 square with large fonts. Name it OEMLOGO.BMP

Now place OEMLOGO.BMP and OEMINFO.INI in the following location.

%systemroot%system folder (for Windows 98/ME computers)
%systemroot%system32 folder (for W2K/XP/2003 computers)

And your system properties will now show the OEM and Support Information.

Use OEM Injector to Change OEM Information
  • Download the current version of OEM Injector from the following link.

The downloaded archive is 654 Kb in size and has the following file hash.

SHA256: 1550f6c783edf4762505c6f4dc7aa919ce4d0e2d5c3addb93b0bbe171c065e11

Extract the archive using 7Zip or other software that supports.rar files.
Execute the unsigned standalone executable [OEM Injector.exe ; 1.72 Kb] to open the software. No installation is required.
The software can run on Windows XP to Windows 7. So if your are using an earlier version of Windows use the manual trick.
The software GUI is clean and exactly the settings that is required. It is not resizable and multiple instances is allowed.
The software is multilingual, supports English and Russian language.
To clear the current OEM Information, click on Clear.
To add custom OEM Information, type the Manufacturer and Model name and browse for image to be used as logo.

It supports .bmp, .jpg, .png and .gif image formats. If selected image is a rectangle, you may choose the part of it to crop into a square by clicking one of the radio buttons on the right. If its is square, you will not have to do anything.
To set the entered information as the OEM Information, click on Install. You will find the changes by going to System Properties.

The manual can be found in the About section of the software, in the product webpage and in the readme file that comes along with the standalone executable.
The software uses minute system resources.

My Verdict

If you like manual control on your PC, go through the steps mentioned above to change the OEM Information, else use the software OEM Injector. If you using a PC with earlier version of Windows that XP, you have to use the manual tricks anyway. About the software, it is well written and is efficient. I just want it to be distributed as a Zip archive, since by default Windows can open that kind of archive only.
