IObit Uninstaller vs O&O AppBuster

IObit Uninstaller is a Windows utility for removing programs, Windows apps, and related leftovers. Its free version includes batch uninstall, drag-and-drop uninstall, Windows app removal, and automatic cleanup of leftover items.

Pro adds automatic removal of leftover files, folders, and registry traces, plus premium technical support. The 1-PC Pro plan is listed at $14.77 per year, and the 3-PC Pro plan at $16.77 per year; both include a 60-day money-back guarantee. The 3-PC plan includes family sharing and lists dedicated support for all PCs. The latest release adds support for 39 languages. IObit Uninstaller is listed for Windows only.
