About this tag
The disk space bug tag covers a Windows 11 storage problem involving the CapabilityAccessManager.db-wal file, a background database log used by the Capability Access Manager service. User reports described the file growing silently and consuming tens, hundreds, or reportedly more than 500 gigabytes of disk space, making the issue difficult to detect and diagnose. The tagged coverage focuses on Microsoft’s June 23, 2026 optional preview update, KB5095093, which includes a fix for the runaway disk usage. It also provides context on how privacy-sensitive app access and hardware permissions relate to the affected Windows service.
