    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 (KB5094041).

    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.
