O&O AppBuster

O&O AppBuster is a free Windows utility for managing and removing applications. It supports batch uninstalling, forced uninstalling, and scans for leftover items after removal. A portable version is available, and the listed plan requires no installation. The supplied capability lists also include backup and recovery functions, drive and boot optimization, startup management, and data wiping. Recovery sources include hard drives, partitions, SSD drives, memory cards, USB sticks, and digital cameras. File preview and bootable recovery are listed. Optimization can be scheduled, run automatically, or performed at boot time. Scheduled shredding, free-space wiping, drive wiping, and certified overwrite methods are included. Compatibility information differs: one list names Windows 7–10 and several Windows Server releases, while another names Windows 10 and 11. Install monitoring and junk cleanup are both listed as unavailable.

O&O AppBuster centers on free Windows app removal while listing broader recovery, optimization, and wiping capabilities. Check the applicable Windows support list before deployment, especially where the two supplied compatibility ranges differ.

It suits Windows users who want portable app removal with batch, forced, and leftover scanning options. It may also interest users needing listed recovery, optimization, or wiping tools.
