Conclusion
IrfanView (64-bit) is a versatile and widely used image viewer and editor that integrates deeply into the Windows operating system through file associations, shell extensions, and registry entries. As a result, standard uninstallation methods may not be sufficient to fully remove it from your system.
From a professional standpoint, while native tools like the Settings app and Control Panel are suitable for basic uninstallations, they often fail to deliver a thorough cleanup.

For a truly effective and hassle-free experience, Perfect Uninstaller stands out as the most reliable choice. With a success rate of up to 98–100%, it ensures that IrfanView (64-bit) and all its remnants are removed permanently from your system.
However, always exercise caution when downloading third-party software — verify the source and consider opting for a paid or premium version for enhanced safety and support.
In summary, while built-in Windows tools provide partial solutions, Perfect Uninstaller remains the superior option for achieving a clean, optimized, and secure system after uninstalling IrfanView (64-bit).
