| Accept changes made outside O&O ShutUp10 | Switch on the Overview tab of the Premium Edition. While it is on, automatic protection does not reset settings that were changed in Windows or another program; the changes are shown as differences from the profile. |
| Add-Only | Application mode of a profile. Applies the values of the settings contained in the profile and leaves all other settings unchanged. |
| AI removal | Feature on the AI tab that disables the Copilot and Recall settings, removes Copilot applications, and securely deletes stored Recall data. |
| Application mode | Determines how a profile is applied: Add-Only or Replace-All. |
| Automatic protection | Premium feature. The background service monitors the privacy settings and re-applies the configured values after Windows updates, policy changes, or other modifications. |
| Buffered changes | Setting changes made in Edit Mode that have not been written to the system yet. They can be applied, discarded, or saved as a profile. |
| Built-in profile | A read-only profile delivered with the Premium Edition, for example Recommended settings, Office, Gaming, Family, or Total privacy. |
| Client | The user-facing application of the Premium Edition. It communicates with the background service and does not need administrator rights. |
| Copilot | Microsoft's AI assistant in Windows. O&O ShutUp10 can disable it and remove its applications. |
| Current User | Tab with the settings stored for the signed-in user account (HKEY_CURRENT_USER). |
| Differences from profile | List in the Premium Edition of settings whose current value differs from the applied profile, with origin and time of the change where known. |
| Edit Mode | Mode in which setting changes are buffered instead of applied immediately, so they can be reviewed and applied together. |
| Factory settings | The command Actions → Undo → All settings ("factory settings") resets every privacy setting to its Windows default. |
| Hybrid Mode | Option of automatic protection. Settings that an external authority such as domain Group Policy reverts repeatedly are excluded from protection. |
| Initial settings | The state recorded the first time O&O ShutUp10 ran on the computer. It can be restored with Actions → Undo → Restore initial settings. |
| Linked setting | A setting that exists on both the Current User and the Local Machine tab. When the machine-wide value changes, O&O ShutUp10 offers to align the user value. |
| Local Machine | Tab with the settings stored for the entire computer (HKEY_LOCAL_MACHINE). Writing them requires administrator rights or the background service. |
| Padlock | Marks a setting enforced by a global configuration file of the organization. The setting is read-only on this computer. |
| Profile | A named, saved set of settings in the Premium Edition (.pcfg file). Profiles can be created, duplicated, imported, exported, and applied. |
| Recall | Windows Copilot+ feature that stores screenshots of the screen activity and makes them searchable. O&O ShutUp10 can disable it and delete its data. |
| Recommendation level | Classification of every setting: Recommended, Limited, or Not recommended, depending on the possible impact on Windows functions. |
| Replace-All | Application mode of a profile. Applies the profile and additionally switches off active settings that are not contained in it. |
| Secure Boot certificates | The Secure Boot tab shows whether the device uses the current Microsoft Secure Boot certificates or needs an update. |
| Service | The Windows service of the Premium Edition. It holds the required privileges, applies settings, and provides automatic protection. |
| Session | All changes made between starting and closing O&O ShutUp10. Each session is one entry of the undo history. |
| Setting ID | Short identifier of a setting, for example M003 or L005. Used in settings files and when searching the list. |
| Settings file | Text file (.cfg) with setting IDs and their states, exported and imported by the Free Edition. |
| System restore point | Windows snapshot that O&O ShutUp10 offers to create before changes, so the system can be rolled back with Windows System Restore. |
| Telemetry | Diagnostic and usage data that Windows sends to Microsoft. O&O ShutUp10 reduces it to the lowest level the Windows edition allows. |
| Toggle switch | Switch next to each setting. Green means the privacy protection is active, red means the setting is not applied. |
| Undo history | Record of the last ten sessions. Any session can be undone, restoring the values the settings had before the change. |
