Deleting a file from the Recycle Bin displays an internal filename in the dialog

| Confirmed | KB5094042 2026-06-09 | Last updated: 2026-06-18, 20:53 PT Opened: 2026-06-18, 12:03 PT |
When permanently deleting a single item from the Recycle Bin, the confirmation dialog displays the internal Recycle Bin filename (for example, $Rxxxxx.ext) instead of the original filename. The Recycle Bin itself correctly displays the original filename, and restoring the item also restores it using the original filename.
This issue occurs after installing the Windows security update released on June 9, 2026 (KB5094042).
Workaround: A workaround is available for affected devices. To apply this workaround in your organization and mitigate the issue, please contact Microsoft’s Support for business.

Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.
Affected platforms:
- Client: Windows 8.1; Windows 7 SP1
- Server: Windows Server 2012 R2; Windows Server 2012; Windows Server 2008 R2 SP1; Windows Server 2008 SP2
Workaround: Do one of the following:
- Perform the operation from a process that has administrator privilege.
- Perform the operation from a node that doesn’t have CSV ownership.
Next steps: Microsoft is working on a resolution and will provide an update in an upcoming release.
