Microsoft has taken steps to rectify a significant issue affecting Windows 11 users, specifically concerning a permissions-related folder that has been consuming an excessive amount of storage space. The company has rolled out an optional update in June 2026, identified as KB5095093, aimed at improving disk space utilization for the CapabilityAccessManager.db-wal file.
This particular file, which is installed by default on Windows 11 systems, plays a crucial role in managing app permissions. However, numerous users have reported alarming growth in the file size, with some experiencing it ballooning to as much as 500GB. Others have noted increases ranging from 12GB to 200GB, raising concerns about storage management and system performance.
While Microsoft has not provided a detailed explanation for the underlying cause of this anomaly, reports suggest that the file’s size may be expanding due to Windows 11 continuously logging repeated events related to access requests and privacy controls, including location data. This behavior has understandably led to frustration among users who rely on their devices for both personal and professional tasks.
How to Install the Update
If you find yourself affected by this issue, installing the update is straightforward. Simply navigate to your Settings menu, select “Windows Update,” then proceed to “Advanced options,” and choose “Check for optional updates.” From there, you can select the June 2026 update for installation.
As Microsoft continues to address these concerns, users are encouraged to stay informed about updates that can enhance their experience and optimize system performance.
