About this tag
The disk space issue tag covers a documented Windows 11 problem involving runaway storage use by CapabilityAccessManager.db-wal, a background database log associated with the Capability Access Manager service. Reports described the file consuming tens or hundreds of gigabytes, with one account exceeding 500 GB, making the issue difficult to spot and diagnose. Coverage focuses on Microsoft’s June 23, 2026 optional preview update, KB5095093, which includes a fix for the excessive disk usage. The topic also highlights how a quiet background service tied to app access, privacy-sensitive hardware, and permissions can create persistent storage problems without obvious system errors or clear explanations.
