Is there software which will analyze all of the applications on the PC and display a list indicating the name, date last used, whether it was purchased or on trial, trial expiration, serial number, website source, etc.?
For this job I would recommend "All My Software". The application will display all the items installed on your computer regarding software applications. Make sure that after you download the application to use the form at the bottom of the download page to request a licence key to activate the software which is free by the way.
