It seems like you are experiencing an issue with your Windows 7 desktop background displaying as black and not changing even when switching themes. This could be due to various reasons such as a corrupted system file, a background setting issue, or a problem with the theme. Here are some troubleshooting steps you can try to resolve this issue: 1. Check Wallpaper Settings: - Right-click on the desktop and select "Personalize." - Choose a different wallpaper from the provided options and see if it applies correctly. - If the wallpaper still appears black, proceed to the next steps. 2. System File Check: Run a system file check to scan and repair any corrupted system files that may be causing the issue. - Open Command Prompt as an administrator by typing "cmd" in the Start menu, right-clicking on "Command Prompt," and selecting "Run as administrator." - In the Command Prompt window, type the following command and press Enter: sfc /scannow - Wait for the scan to complete. If any issues are found, the tool will attempt to fix them automatically. 3. Check Themes: - Try switching to a different built-in theme to see if the issue persists. - If the problem is only with custom themes, try resetting the theme to default settings. 4. Check Background Settings: - Right-click on the desktop and select "Personalize." - Click on "Desktop Background" at the bottom of the window. - Ensure that the correct background image is selected and set to fill, fit, stretch, tile, or center as desired. 5. Update Graphics Drivers: Make sure your graphics drivers are up to date. Outdated or corrupt graphics drivers can sometimes cause display issues. 6. Run Windows Update: Check for any pending Windows updates and install them. Updates often contain bug fixes and improvements that could address the problem. 7. Advanced Troubleshooting: If the issue persists, consider performing a system restore to a point before the problem started or reinstalling Windows 7. Remember to backup your important data before making any significant changes to your system.
