Conclusion
OpenGL Extensions Viewer is a useful diagnostic tool for understanding your system’s graphical capabilities, but like any utility, it deserves a clean uninstallation when no longer needed. While native Windows tools such as the Settings app and Control Panel can handle basic removal, they often fail to eliminate all traces — particularly configuration files, temporary caches, and registry entries.
From a professional standpoint, manual cleanup ensures the most thorough removal but is time-consuming and technically demanding, making it suitable primarily for advanced users or system administrators.
For most users, Perfect Uninstaller stands out as the most effective and user-friendly solution. With a success rate of up to 98–100%, it ensures that OpenGL Extensions Viewer and all its remnants are permanently removed from your system — helping maintain optimal performance, privacy, and system hygiene.
However, always exercise caution when downloading third-party tools — verify the source authenticity, read user reviews, and consider investing in a 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 OpenGL Extensions Viewer.
