Deactivating a Local User
Deactivating a user means that a user will not be able to log in, though their personal information and all their activities, files, history, and other information will be kept in the system. At any moment you can reverse this change and reactivate the user account.
To deactivate a local user:
1. Go to «Administration» > «Users».
2. Double-click on a user and clear the «Active» check box.
3. Click «Save & Close».
