O&O AppBuster, published by O&O Software GmbH and currently at version 1.4.1345, is a lightweight, portable utility designed to give Windows 10 and 11 users granular control over the operating system’s pre-installed Microsoft and third-party applications. Because the program runs without installation, it can be launched immediately from a USB stick or any folder, presenting an intuitive dashboard that lists every bundled app—visible or hidden—and distinguishes between those supplied by Microsoft and those added by the device manufacturer. With a simple checkbox system, administrators, power users, and novices alike can permanently uninstall unwanted bloatware, advertising apps, or trial packages that consume storage and bandwidth, while a built-in restore function can reinstate any program that was removed in error. All changes are logged and can be rolled back through automatically created Windows restore points, ensuring that corporate deployment or personal experimentation can be undone without system reinstallation. The tool is explicitly licensed free of charge for private, business, and educational environments, making it equally suitable for IT departments preparing standardized Windows images, technicians refurbishing resale machines, or home owners seeking a cleaner Start menu. Although only two major release versions have appeared so far, each has remained fully compatible with every Windows 10 and 11 edition, including cumulative feature updates. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
