Microsoft Patches Windows 11 Bug That Let 500GB Log File Swell
3 articles · Updated · Windows Central · Jul 7
Summary
July’s Patch Tuesday update fixes a Windows 11 storage bug that let the CapabilityAccessManager.db-wal file balloon to 500GB on some PCs, with an optional update available now.
Microsoft tied the issue to repeated app-permission access events being logged inefficiently by Capability Access Manager, which handles permissions such as location and camera access.
The update’s changelog says it improves disk space usage for the file, though Microsoft provided little technical detail beyond the storage fix.
Users can wait for the normal rollout if their PCs are functioning, because deleting the file manually can cause problems—one Reddit user lost Wi-Fi connectivity until removing the folder and restarting.
