This article explains how to change the Windows Logon logo. That’s the small logo at the bottom of the screen which is displayed on the log on/off screen, the control+alt+delete screen and the lock screen.
Problem: We want to change the Windows logo displayed when logging on and off.
There are two different solutions. Both involve replacing an image in “Basebrd.dll” with your own, but the first method uses a handy small application called Windows Logon Branding Changer to do all the heavy lifting for you. You will need administrative privileges for both methods.
First (Easier) Solution
- Download Windows Logon Branding changer. (It was created by DeviantArt user myjuman, who has taken it off his site recently.)
- Open the program, making sure the program has administrative priviliges and access to the Windows folder.
- Select a .PNG file to replace the logo with. Keep in mind the original logo size of 350×50 pixels. You may choose bigger images, but they will be scaled down to fit the original.
- Note: Unlike the method below the .PNG should have a transparent background if you want it to only display the logo. Any background colours will show up as they are.
- To restore the default image just click the “Restore” button.
Second (Manual) Solution
- Manually go to the Windows folder on your main hard drive. Within this folder, go to the “Branding” folder, and within that to the “Basebrd” folder. You will a path that will look like “C:WindowsBrandingBasebrd”.
- Within this folder, take ownership of “Basebrd.dll”. This can be done by maneuvering to the “C:WindowsBrandingBasebrd” folder in CMD, and using the command “takeown /f basebrd.dll” (Note: you might still have to give yourself administrative/full permissions to edit the file. Done by right clicking, selecting “Properties” and going to the “Security” tab.)
- Use a program such as the completely free Resource Hacker to open the “Basebrd.dll” file.
- In that file, replace the bitmap called “120” (1033 is the language, the folder name is the resource name) with a .BMP image of your own choice, with dimensions of 350×50 pixels.
- The image must have a black background (or the same as the original being replaced). If it doesn’t, the entire image will fail to show up.
- Note: This method is not recommended since it comes with a bunch of problems. Often images will not show up even with a black background, or the Windows logo will disappear, but instead of your logo appearing it just leaves a “shadow” of the original text. Fixes involve even more in-depth editing of Windows. Therefore we strongly suggest using the first, much easier solution.
Protip: In the “Basebrd” folder or one of its subfolders you will find a “basebrd.dll.mui” file. If you open it with Resource Hacker or an equivalent program, you will find the String values used to display version/copyright info, as well as information about Windows. You may edit most of these strings without problems. They are, for example, shown in the System properties tab.
Remember to always make a backup of any files you are editing and to create a system restore point before you start your project.
