How to undo everything and remove NyxBoost

  1. Open Recovery and press “Revert” on the changes you want back. A revert does not overwrite what you or Windows changed later.
  2. In Settings, turn off starting NyxBoost with Windows and any scheduled automation.
  3. Close NyxBoost (tray icon → Exit) and delete NyxBoost.exe.
  4. Delete the folder %LOCALAPPDATA%\NyxBoost (settings, log, change history). Delete it last: without it the program can no longer undo its changes.
  5. Windows restore points made before changes stay in the system: System Restore can take the PC back to the state before them.
