Sometimes, terrible happen to our computer/laptop. It probably because of viruses, crashes, or another reasons. If the terrible goes worse, we often do not have a choice to fix, except re-installing the Windows Application. It is really wasting our time.

Yeah, sometimes we do not remember where did we put the activation data of some program.
