Several applications have been created to automatically decrypt the information and display them in a readable form to the user. One of those programs is UserassistView by Nirsoft.

The portable software program displays a list of item names, their index number, times they were started, modified time and ClassID.
It is possible to delete selected or all entries from the listing. The UserAssist key will however be automatically filled with new information from that point on so that it might be a better idea to schedule a regular cleaning job with a program like CCleaner.
The program history can also be saved as text, csv or html files for further inspection. UserAssistView is compatible with all Windows NT based operating systems including Windows 7. It can be downloaded directly from the Nirsoft homepage.
