How to Fix: Graphics performance worse after DDU and Windows Update not working + DISM

The issue you're experiencing with your graphics performance worsening after DDU and Windows Update, along with DISM not working, is likely due to the presence of malware or corrupted system files. The '0x800f081f' error from Windows Update and '0x800f0915' error from DISM indicate that there are issues with the Windows Update process, which may be caused by malware or corrupted system files. The fact that a Trojan was detected on the DDU installer, but it didn't trigger detection, suggests that the malware might have been removed, but not all corrupted files were cleaned.

⚠️ Common Causes

• The presence of malware or corrupted system files.
• The DDU installer not being able to detect and remove all corrupted files.
• The Windows Update process being affected by corrupted system files or malware.

💡 Conclusion

To resolve the issue, it's recommended to perform a clean installation of Windows or use a System File Checker (SFC) scan to repair corrupted system files. Additionally, ensure that all drivers are up-to-date and consider reinstalling your graphics drivers using an official AMD uninstaller or DDU. Regularly backing up your important files and data can also help prevent similar issues in the future.
