System Cleanup

Removes leftover files and artifacts commonly dropped by malware, installers, and failed processes.

Precision Cleanup. Real Performance Gains. Zero Risk.

The Xernox System Cleaner is a precision Windows optimization utility designed to remove non-essential data that accumulates during normal system use, software installation, application crashes, and malware execution. Temporary files, cache artifacts, and residual runtime data can persist long after they are needed—interfering with application behavior, consuming disk space, and degrading overall system reliability. Xernox targets these disposable data locations with a controlled, permission-aware cleanup engine that prioritizes system integrity.

Temporary & Cache Data Removal
Cleans Windows TEMP, user TEMP, browser caches, thumbnail caches, Windows Update cache, and Prefetch data.
Malware & Installer Residue Cleanup
Removes leftover files and artifacts commonly dropped by malware, installers, updaters, and failed processes after execution or remediation.
Runtime State Correction
Eliminates corrupted or stale cache data that can cause applications to malfunction or fail to initialize correctly.
Safe-by-Design Operation
No registry cleaning, no system file modification, no services, and no persistent changes to Windows configuration.

Fast and Reliable System Cleanup

Built in native C++ for maximum performance and minimal overhead, the cleaner executes rapidly with negligible CPU usage and no background services. Every operation is transparent and measurable, providing real-time feedback and a detailed post-run summary that reports exactly what was removed and how much space was recovered. The result is a faster, more stable system without risk, guesswork, or hidden side effects.

Permission-Aware Cleanup Engine
Automatically skips locked, in-use, or protected files to prevent instability or forced deletions.
Iterator-Safe Deletion Logic
Collects targets before removal to avoid filesystem corruption and partial cleanup states.
Administrator-Aware Optimization
Expands cleanup scope when elevated, while remaining fully functional in standard user mode.
Transparent, Verifiable Results
Reports exact file counts, reclaimed storage, and execution time after every cleanup run.
