How to Uninstall WPS Office

WPS Office is a popular office productivity suite developed by Kingsoft, offering alternatives to Microsoft Word, Excel, and PowerPoint. It includes word processing, spreadsheet creation, presentation tools, and PDF editing features. While WPS Office is widely used for its lightweight design and compatibility with Microsoft Office file formats, some users may want to uninstall it due to performance issues, system conflicts, or switching to other office suites.

However, like many software applications, WPS Office can leave behind residual files, registry entries, and background processes, making complete removal challenging. This guide outlines several methods to fully uninstall WPS Office, including built-in Windows tools, manual cleanup, and the use of Perfect Uninstaller—a professional third-party tool that ensures thorough removal. We’ll also cover key differences between 32-bit and 64-bit systems, as well as Windows 7, 10, and 11 during the uninstallation process.

Conclusion and Professional Opinion

Uninstalling WPS Office is more complex than it appears due to its tendency to leave behind residual files, registry entries, and persistent background services. While native tools like Windows Settings and Control Panel offer a good starting point, they often fail to completely clean up the system.

Manual cleanup provides deeper results but requires technical expertise and carries risks—especially when editing the registry. For most users, especially those without advanced technical skills, the safest and most effective solution is to use Perfect Uninstaller, which guarantees a comprehensive and secure removal of WPS Office and all its associated data.

From a professional standpoint, we recommend beginning with built-in OS tools, followed by manual cleanup if necessary. If system anomalies persist or maximum cleanliness is required, turn to Perfect Uninstaller to ensure optimal performance and system integrity.

Always download third-party tools from official or verified sources to avoid malware infection or system compromise. By choosing the right method based on your system version (Windows 7, 10, or 11) and experience level, you can safely and effectively remove WPS Office from your computer.
