Undo History
O&O ShutUp10 records the changes you make, so you can take them back later without having to remember which switches you moved. The undo history is available in both the Free Edition and the Premium Edition.
All undo commands are grouped in the Actions → Undo submenu.
Sessions
Changes are recorded per session — everything you change between starting and closing O&O ShutUp10 forms one entry, no matter how you changed it. Toggling three switches by hand, applying a profile, and applying all recommended settings all produce entries of the same kind.
An entry records, for every setting it touched, the value that setting had before the change. Undoing therefore restores the previous state rather than simply switching everything off. A setting that had no value at all before the change is returned to having none.
The last 10 sessions are kept. When a new session is recorded, the oldest one is dropped.
Undoing the Last Session
The first entry in the Actions → Undo submenu names the session it would take back, for example:
Undo changes of 31/07/2026 13:22 (2 settings)
Selecting it restores every setting in that session to the value it had beforehand. The entry is hidden when there is nothing to undo.
Undo History
Actions → Undo → History… opens a list of the recorded sessions, newest first. Each entry shows when it was recorded, how many settings it changed, and — where the session consisted of a single kind of operation — what that operation was: manual changes, applied profile, applied recommended settings, or applied all settings.
Selecting an entry lists the settings it changed, each with the direction of the change (for example on to off), so you can see what rolling back would put back before you commit to it.
Rolling back to an entry also rolls back every newer entry above it. The history is a stack, not a set of independent items — you cannot undo one session from the middle and keep the ones after it.
Sessions are removed only after their settings have been restored successfully. If the background service cannot be reached or a change fails, the affected history entries remain available for another attempt and O&O ShutUp10 reports the error. The restore runs in the background, with the dialog controls temporarily disabled, so an unresponsive service does not freeze the application window.
Restore Initial Settings
Actions → Undo → Restore initial settings restores the state that was recorded the very first time O&O ShutUp10 ran on this system — in other words, how the machine was configured before you used the program at all.
This is independent of the session history: it works even when the history is empty, and it reaches further back than the ten recorded sessions.
All Settings ("factory settings")
Actions → Undo → All settings ("factory settings") resets every privacy setting to its Windows default.
The factory reset is itself recorded as a session in the undo history. You can therefore undo it like any other session. The reset also removes policy subkeys that are left empty, preventing Windows from continuing to show Some settings are managed by your organization solely because of remnants from an earlier O&O ShutUp10 configuration.
This is not the same as Restore initial settings. Factory settings apply the Windows default to every setting, regardless of how your system was configured before you first used O&O ShutUp10. If you had already changed privacy settings by hand — or with another tool — before installing O&O ShutUp10, those changes are reset as well.
Changes Made Outside O&O ShutUp10
The history covers changes made through O&O ShutUp10. Settings that Windows itself resets — for example during a feature update — are not recorded as a session and cannot be taken back through the undo history. The Premium Edition's Automatic Protection is the feature that deals with that case.
For changes that affect many settings at once, a system restore point is still the broader safety net. You can create one from Actions → Create a system restoration point before you start.
