Microsoft has confirmed a bug affecting the Recycle Bin across all supported versions of Windows following its June 2026 Patch Tuesday update. The glitch causes the confirmation dialog to display an "internal" filename instead of the user-friendly filename when deleting files, although the actual file and its deletion process remain unaffected. The issue affects various Windows client and server versions, including Windows 11 (versions 26H1, 25H2, 24H2, 23H2), Windows 10 (versions 22H2, Enterprise LTSC 2021, Enterprise LTSC 2019, Enterprise LTSB 2016), and Windows Server (2025, 2022, 2019, 2016, 2012 R2, 2012). Microsoft is developing a permanent solution, but it is unclear when it will be released. Commercial customers can contact Microsoft Support for Business for a workaround.
