The Windows 11 Storage Bug has finally been addressed by Microsoft after causing serious storage problems for many users. Some Windows 11 systems unexpectedly lost hundreds of gigabytes of available disk space because of a system file that kept growing without warning. In extreme cases, the file reportedly reached nearly 500GB, leaving users confused about where their storage had gone. Microsoft has now released a fix through its optional June 2026 update, giving affected users a reliable solution.
What Was the Windows 11 Storage Bug?
The Windows 11 Storage Bug was linked to a system file named CapabilityAccessManager.db-wal. This file is part of Windows’ Capability Access Manager, a service responsible for managing application permissions.
Every time an application requests access to features like the camera, microphone, location services, or other privacy settings, Windows records those events. Normally, this information occupies very little storage. However, due to a software issue, Windows repeatedly logged the same permission events, causing the database file to grow continuously.
Instead of remaining a few megabytes in size, the file expanded to several gigabytes, and in some reported cases, hundreds of gigabytes.
How Serious Was the Issue?
The impact of the Windows 11 Storage Bug varied depending on individual systems.
Some users noticed only a few gigabytes disappearing, while others lost between 50GB and 200GB of available storage. A handful of affected systems reportedly experienced file sizes approaching 500GB.
For users with smaller SSDs, this became a major issue. The unexpected storage consumption reduced system performance, prevented software installations, and even caused Windows update failures due to insufficient free disk space.
Since the file belonged to the operating system, many users struggled to identify the source of the problem.
Microsoft Releases the Official Fix
Microsoft has now resolved the issue through the KB5095093 preview update for Windows 11.
The company confirmed that the update improves how Windows manages disk usage related to the Capability Access Manager database. Although Microsoft has not shared the exact technical cause behind the excessive logging, the fix prevents the system file from continuing to grow uncontrollably.
The update is currently available for:
- Windows 11 Version 24H2
- Windows 11 Version 25H2
Users who install the update will receive operating system builds 26100.8737 and 26200.8737, depending on their version.
How to Install the Update
Anyone affected by the storage issue can install the optional update manually.
Simply follow these steps:
- Open Settings
- Select Windows Update
- Click Advanced Options
- Open Optional Updates
- Install KB5095093
Microsoft has also confirmed that this fix will be included in the regular monthly security updates. Users who prefer not to install preview updates can simply wait for the next scheduled Windows update.
How to Check if You’re Affected
If you’ve noticed your available storage decreasing without explanation, it’s worth checking your system.
Navigate to:
Settings → System → Storage
Pay close attention to the System and Reserved storage category.
If this section occupies significantly more space than expected, the oversized Capability Access Manager file may be responsible.
While Windows doesn’t directly display the file size within Storage Settings, an unusually large System category is often the first warning sign.
Don’t Delete the File Manually
Some users attempted to fix the problem by deleting the database file themselves or disabling the related Windows service.
Microsoft strongly advises against this.
Capability Access Manager is responsible for managing important permission controls throughout Windows. Removing the wrong system files or disabling essential services may create additional problems.
Several users who manually deleted the file reported issues including:
- Loss of Wi-Fi connectivity
- Network problems
- Permission-related errors
- System instability
Installing Microsoft’s official update remains the safest and recommended solution.
Other Improvements Included
Although fixing the storage issue is the highlight, KB5095093 also introduces several additional improvements across Windows 11.
Some notable enhancements include:
Better Taskbar Notifications
Microsoft has refined notification badges displayed on the taskbar, making alerts clearer and easier to understand.
Improved Network Features
The update includes improvements for:
- Shared network connections
- Netlogon authentication
- Secure Boot certificate delivery
These changes improve reliability, particularly for enterprise users.
Emoji Panel Changes
Windows now replaces Google’s Tenor integration with GIPHY as the default GIF provider inside the emoji panel.
Users searching for animated GIFs will now see content powered by GIPHY instead.
Recycle Bin Fix
Microsoft also corrected an issue where permanently deleted files occasionally displayed internal filenames instead of their original names.
Although minor, this improvement enhances the overall user experience.
Why This Fix Matters
Storage-related bugs are among the most frustrating problems Windows users encounter.
Unlike application issues that affect only one program, the Windows 11 Storage Bug consumed valuable SSD space silently in the background. Many users had no idea why their storage continued disappearing until they manually investigated.
By resolving the excessive logging problem, Microsoft prevents unnecessary storage consumption while maintaining proper management of Windows privacy permissions.
This also highlights the importance of keeping Windows updated, especially when system-level bugs are identified.
The Windows 11 Storage Bug has finally been resolved after causing unexpected storage loss for many users around the world. Microsoft’s latest update stops the Capability Access Manager database from growing uncontrollably, protecting users from losing hundreds of gigabytes of valuable storage.
If you’ve experienced unexplained storage usage on your Windows 11 PC, installing KB5095093 or waiting for the next cumulative Windows update—is the best course of action. With additional improvements to networking, notifications, and system reliability, this update delivers several worthwhile enhancements beyond the storage fix.
Keeping your operating system updated remains the simplest way to avoid issues like this and ensure your PC continues running smoothly and securely.
