• Unactivated Windows: It limits customization options, blocking most settings from the Personalization menu, although there are small tricks to circumvent these restrictions.

Methods to change the logon background in Windows

Method 1: Change the background to a solid color using the Registry Editor

This method is valid especially for Windows 10 and allows replace the login image with a plain color. It doesn't require any third-party programs, but it does require modifying the Windows registry, so it's recommended to make a backup first:

1. Balance Win + R To open the Run window, type regedit and hit Enter.
2. Navigate to the route HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\System.
3. In the right pane, right-click and select New > DWORD (32-bit) Value.
4. Name it like DisableLogonBackgroundImage and assign it the value 1.
5. Close Registry Editor and click Win+L to check the change on the login screen.

The background color will be the accent color that you have configured in your system. You can change it from Settings > Personalization > Colors.

Customize the background color from the hidden Control Panel

If you want a different color than the standard options, you can open the old color selection interface with this command:

rundll32.exe shell32.dll,Control_RunDLL desk.cpl,Advanced,@Advanced

From there, you can adjust hue, brightness, and saturation to choose an exact color.

Method 2: Replace the login image with a custom one

Windows doesn't officially make it easy to change your login picture, but you can try it with specialized third-party softwareYou should be aware that modifying system files is not approved by Microsoft and may involve some risk. The two most recommended tools are:

• Windows 10 Login Background Changer: It's a free utility that allows you to select any image as your login background. To use it, download it, run it as Administrator, and choose the image you want. Click "Change Background" and restart the login screen.
• Login Lockscreen Image Changer: Lighter and simpler, ideal if you want a stable and hassle-free application.

Both programs work by modifying the PRI file where Windows stores the default logon background image. It is recommended to have a restore point or backup before using such tools, as Windows updates may again block the change or cause the program to stop working.

Method 3: Configuration with Group Policies and Advanced Management

In business environments or for those who manage multiple teams, it is possible to apply group policies (GPOs) to set the login background on all devices.

1. Image location: Place the image you want to use in %windir%\System32\oobe\info\backgroundsIf those folders don't exist, create them.
2. File name: The image should be called BackgroundDefault.jpg y do not exceed 256 KB.
3. Permissions: Give domain computers read permissions to that folder.
4. Enable the policy: Go to 'Administrative Templates > System > Logon' and enable the policy "Always use a custom login background".
5. Update policies: Run the command gpupdate /force to apply the settings.

This method is especially useful for organizations, as it allows for standardized visual appearance across all devices and facilitates remote management.

Method 4: Manually editing files in C:\Windows\SystemResources

Some advanced users seek to directly modify system files in C:\Windows\SystemResources, where operating system resources are stored, including the login image. This procedure can be risky and is only recommended if you have experience in Windows system administration..

• Locate the image file you want to replace in the SystemResources folder, usually associated with “Windows.UI.Logon.pri”.
• Make a backup copy of the original file and replace it with your image using the same resolution and format.
• To edit PRI files you may need special tools like PRI Editor.
• When finished, restart your computer to apply the changes.

Remember: Any major Windows update can restore system files and remove customization.

Customizing the Start Menu and Lock Screen Layout

Not only can you customize the login background. Windows also allows modify the Start menu layout (app location, icons, colors, and more) and the lock screen. For advanced users or administrators, you can export your customized settings to XML or JSON files and apply them to other devices.

• Prepare the layout: Customize the Start menu of the reference computer.
• Export configuration: Usa PowerShell with the command Export-StartLayout to create an XML (Windows 10) or JSON (Windows 11) file.
• Apply the design: Import the file to other devices using group policies or provisioning scripts.

This feature is ideal for companies that want a consistent environment across all teams.

Options to change the background in Windows without activating

If your system is not activated, customization restrictions are noticeable (you can't change the background from Settings), but there are still useful alternatives:

• You can right-click on an image in your file explorer and choose “Set as desktop background.”
• With browsers like Mozilla Firefox, you can right-click on an image from the Internet and use the “Set image as Desktop Background” option.
• The method works best if the image has the same resolution as your monitor to avoid distortions.
• You can also modify the registry in HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System adding the path of the image you want to use as a background.

Don't forget to always keep the images in the folder where you set them up., because if you delete or move the file, Windows will not be able to display that image as a background and will revert to the default.
