Microsoft fixes Windows 11 folder consuming excess storage
Microsoft has released a fix for a Windows 11 bug that caused a specific folder to consume multiple gigabytes of storage. The patch is included in the optional June 2026 update.
Microsoft is addressing a Windows 11 bug that caused a specific folder to grow excessively, consuming several gigabytes of storage space.
The issue affected the CapabilityAccessManager.db-wal file, which is related to application permissions. Users have reported this file ballooning to hundreds of gigabytes, causing significant issues with device storage.
The fix, included in the optional June 2026 update (KB5095093), specifically addresses disk space usage for this file. While Microsoft has not detailed the exact cause of the unexpected growth, some minor, temporary expansion is considered normal operation.
The patch is available to all Windows 11 users who install the latest optional update. Microsoft typically rolls out fixes for such issues in its regular monthly updates.
