Microsoft June 2024 Patch Exposes Recycle Bin Filenames

Key Takeaways

• Microsoft’s June 2026 Patch Tuesday update introduced a cosmetic bug affecting Recycle Bin deletion dialogs.
• When permanently deleting a single file, the confirmation dialog displays an internal system filename (e.g., $Rxxxxx.ext) instead of the original user-facing name.
• The issue impacts numerous Windows client and server versions, including Windows 11, Windows 10, and various Windows Server editions.
• While the bug causes no data loss or security vulnerability, it can lead to user confusion.
• A workaround is available for enterprise clients by contacting Microsoft Support, with a permanent fix expected in a future update.

Microsoft has confirmed a new software defect, inadvertently introduced with its June 2026 Patch Tuesday security update, that alters the display of filenames within Recycle Bin deletion confirmation dialogs. Instead of showing the file’s original name, the system now presents an internal identifier.

Following the installation of the Windows security update KB5094125, released on June 9, 2026, users attempting to permanently remove a single item from the Recycle Bin will observe a confirmation prompt that exhibits the file’s internal system name, such as $Rxxxxx.ext, rather than its original, user-assigned filename.

This issue is strictly cosmetic. The Recycle Bin’s primary file listing and its restoration functions continue to accurately display and recover original filenames without any compromise to data integrity or risk of data loss.

Microsoft officially acknowledged this bug on June 18, 2026. The problem is documented under OS Build 26100.32995, associated with KB5094125. The entry within Microsoft’s Known Issues tracker was last revised on June 18, 2026, at 19:27 PT.

Affected Platforms

The scope of this bug extends across a wide array of Windows client and server operating systems, encompassing:

• Windows 11: versions 26H1, 25H2, 24H2, and 23H2
• Windows 10: version 22H2, Enterprise LTSC 2021, Enterprise LTSC 2019, and Enterprise LTSB 2016
• Windows Server: 2025, 2022, 2019, 2016, 2012 R2, and 2012

The extensive reach of this flaw means it impacts both consumer and enterprise environments, including Long-Term Servicing Channel (LTSC/LTSB) deployments frequently utilized in critical infrastructure and highly regulated sectors.

Although the bug does not lead to data loss, corruption, or pose any security vulnerability, the revelation of internal Recycle Bin naming conventions (identifiable by the $R prefix format) could generate user confusion. This is particularly relevant in corporate settings, where help desk personnel or end-users might become unsure whether they are targeting the correct file for deletion.

In managed IT environments, this discrepancy could also potentially disrupt automated deletion workflows or scripts that rely on parsing dialog outputs for accurate file identification.

Microsoft has confirmed that a workaround is available for enterprise customers affected by this issue. However, organizations must directly contact Microsoft Support for Business to obtain and implement this fix, as no self-service resolution has been publicly released.

The company has indicated that it is developing a permanent solution to be included in a forthcoming Windows update but has not yet provided a specific release timeline.

What You Should Do

• System administrators should actively monitor the Windows Release Health dashboard for official updates regarding a permanent fix.
• Inform end-users about this cosmetic discrepancy to prevent confusion during routine file management tasks.
• Enterprise organizations experiencing issues with automated deletion workflows or scripts should contact Microsoft Support for Business to inquire about the available workaround.
