About this tag
The storage leak tag covers reports of unusually high disk usage in Windows 11, including a problem involving the CapabilityAccessManager.db-wal file. This background database log supports the Capability Access Manager service, which tracks app access to privacy-sensitive hardware and permissions. User reports described the file consuming tens or hundreds of gigabytes, with one report exceeding 500 GB, making the issue difficult to diagnose because it can grow quietly without obvious system errors. Coverage also follows Microsoft’s June 23, 2026 optional Windows 11 preview update, KB5095093, which includes a fix for the runaway disk-usage behavior.
