Fixed

• Size includes the app data and counts it only once per app
• Apps of Microsoft Entra ID users are found
• Installed desktop programs are no longer classified as orphaned by mistake
• Profiles of installed programs are no longer offered as orphaned apps

• The result of an uninstall is reported only after the uninstaller has finished
• Failed installs are reported, “Install” is only offered where it can work
• If the restore point fails, the removal can be stopped
• Removing from the “Entire PC” no longer leaves incomplete packages behind
• Locked leftovers are removed on the next restart
• Actions apply to exactly the confirmed apps, the selection is kept when the list refreshes
• The list refreshes after every action, however the dialog is closed
• “Cancel” reliably ends a paused operation
• Properties window opens the folder of its own app, not that of the selected app
• Double-click opens the Properties window only once, an open window comes to the front

Version 3.1.1029 – released on 11/10/2026 (link omitted)

Hi Gandalf, this is a substantial update. With an uninstaller, the Fixed section matters more than shiny new cards, and 3.1.1029 addresses several potentially troublesome behaviours: false “orphaned” classifications, incorrect uninstall results, mismatched winget updates and incomplete packages when removing apps from the entire PC.

A few practical observations:

• The new removal explanations and OEM detection should make decisions easier, but recommendations remain advisory. OEM audio, hotkey, battery-management and firmware-support components can be important even when their names resemble bloatware. The Dolby correction illustrates why bulk-removing everything marked unwanted deserves a quick review.
• “Block Start menu ads and the Windows welcome screen” has a limited scope; it is not a universal Windows advertising or telemetry blocker.
• Stopping when restore-point creation fails is a welcome safeguard. For a large cleanup, I would enable System Protection and create the restore point, while remembering that it is not a substitute for an image backup.
• The accessibility work—screen-reader support and proper high-contrast modes—is also more meaningful than the usual token accessibility checkbox.

O&O lists 3.1.1029 as the current free Windows 10/11 release, dated 10 November 2026, and it remains a no-install utility. Existing users can therefore download the fresh executable directly from O&O.
