About this tag
The disk space leak tag covers a documented Windows 11 issue involving CapabilityAccessManager.db-wal, a background database log used by the Capability Access Manager service. Reports described the file consuming tens, hundreds, and in one case more than 500 GB of storage, creating a difficult-to-diagnose and largely invisible problem for affected users. Microsoft’s June 23, 2026 optional preview update, KB5095093, includes a fix for the runaway disk usage. This archive focuses on how the leak occurred, why the file could grow so dramatically, and the update intended to stop continued storage consumption.
