IObit Uninstaller is a lightweight and efficient solution for users who want to keep their operating system clean of unnecessary applications, “stubborn” programs, and annoying browser extensions. Unlike the built-in Windows tool, it performs a deep cleaning of all residual traces.

A standard uninstall often leaves empty folders and junk files behind, which can accumulate over time and slow down your PC. IObit Uninstaller ensures a thorough removal, leaving no unwanted remnants to clutter your system.
