KTL - Key Thing Lite is a tiny utility that i mentioned before in my posts. It can display install keys of various applications installed such as MS Office, Adobe etc. It can display Windows install keys as well.
It came in handy a couple of times in the past couple of weeks.
Key Thing Lite reached v.1.19. Now It supports more applications.
