Of course it is possible to revise each of your personal decisions. That could be necessary if you have denied some process which turns out as a good one later. You do so by right clicking on the TeaTimer symbol in the system tray - it is the blue one with the lock. (If you cannot see the symbol, it is probably hidden. Just click on the arrows in the system tray to show all hidden symbols.) A window appears where you have to click on Settings to modify your personal lists of registry changes and processes.

from FAQ] ....How do I edit the Black & White list in resident TeaTimer? FAQ #005
Please right-click the Resident icon in the system tray Spybot S&D resident and select Settings. There you will find four lists for remembered decisions (allowed/denied processes and registry changes). In order to remove an entry, just click on the cross next to it. TeaTimer will then "forget" this decision and you will be asked again the next time.
