"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," Microsoft explained in a Thursday update to the Windows release health dashboard.
What Microsoft says the bug does
Microsoft confirmed a bug tied to the June 2026 security updates that changes the filename shown in the deletion confirmation dialog when a user permanently deletes a single item from the Recycle Bin. According to the company, the Recycle Bin view itself still displays the original filename, and restoring the item returns it to its original name. The company described the problem in a succinct advisory on its Windows release health dashboard and did not provide additional technical details in that update.
Which Windows releases are affected
Microsoft said the issue affects "all supported Windows releases across both client and server platforms" that have installed the June 2026 security updates. The company listed the complete set of affected releases as:
- Client: Windows 11, version 26H1; Windows 11, version 25H2; Windows 11, version 24H2; Windows 11, version 23H2; Windows 10, version 22H2; Windows 10 Enterprise LTSC 2021; Windows 10 Enterprise LTSC 2019; Windows 10 Enterprise LTSB 2016
- Server: Windows Server 2025; Windows Server 2022; Windows Server 2019; Windows Server 2016; Windows Server 2012 R2; Windows Server 2012
Microsoft did not publish metrics describing how widespread the problem is across deployments.
How Microsoft is addressing the problem
Engineers at Microsoft are working on a correction that the company said "will ship to affected systems in a future Windows update." No date or build number for that fix was provided in the advisory.
While the permanent fix was not yet available, Microsoft said a temporary workaround exists for affected devices. That workaround is not published for broad self-service use; instead, Microsoft instructs organizations to contact Microsoft's Support for business to apply the mitigation in their environments.
Other update-related issues Microsoft flagged in June 2026
The Recycle Bin filename anomaly came amid other problems Microsoft has acknowledged in the same update cycle. Earlier in the week, the company confirmed an issue introduced by the June 2026 updates that prevents third-party apps from launching Word, Excel, PowerPoint, Access and other Office applications — or from opening documents in those apps. Separately, Microsoft said it had fixed a known issue that caused the June 2026 security updates to fail on Windows Server 2016 systems that did not have the May KB5087537 security update installed.
What this means for technologists, enterprises, and end users
- Technologists and security teams: Expect a user-facing inconsistency in the deletion confirmation dialog after the June 2026 updates. Microsoft has signaled a forthcoming patch, and teams with affected systems can request the temporary workaround by contacting Microsoft's Support for business.
- Affected enterprises and procurement leaders: The bug spans a long list of client and server releases; organizations should inventory which systems have received the June 2026 updates and coordinate with Microsoft's business support to apply the published workaround where needed until the permanent fix ships.
- End users: The Recycle Bin will continue to show the original filename and restoration will return files under that name, even though the deletion confirmation dialog may display an internal filename such as $Rxxxxx.ext. Users who see the internal filename are therefore seeing a display inconsistency rather than a change to stored filenames.
Microsoft's update-cycle advisories in June 2026 show a mix of display-level and functional issues tied to the same security rollup and a patch for one Server 2016 installation failure. The company has acknowledged the Recycle Bin display inconsistency, provided a path to a temporary mitigation for businesses, and committed to shipping a permanent correction in a future Windows update; it has not, in its public advisory, set a timetable for that release.
