O&O AppBuster

What O&O AppBuster is

O&O AppBuster is a free Windows utility for managing and removing apps. Its listed functions include batch uninstalling, forced removal, and scanning for leftover items. A portable version is available, and the plan is described as freeware with no paid edition or trial period. The listed capabilities also extend to backup, recovery, drive optimization, and data wiping, including boot-time and scheduled optimization, scheduled shredding, free-space wiping, and certified overwrite methods. Recovery sources include hard drives, partitions, SSDs, memory cards, USB sticks, and digital cameras; bootable recovery and file preview are listed too. Compatibility details differ between the supplied Windows lists: one names Windows 7–10 and several Windows Server versions, while another lists Windows 10 and 11. Check support for the Windows version in use rather than assuming both lists describe the same range. Install monitoring and junk cleanup are each specifically listed as unavailable. No paid price is listed for AppBuster.
