About this tag
The storage space issue tag covers a Windows 11 problem involving runaway disk usage from 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 detect and diagnose. Microsoft’s June 23, 2026 optional Windows 11 preview update, KB5095093, includes a fix for the behavior. This tag follows coverage of the update, the affected system component, and the unusually large, persistent storage growth associated with the bug.
