Parsing prefetch files

Prefetch files stored at C:\Windows\Prefetch can be analyzed to show which programs have been run on a Windows computer. Eric Zimmerman's opensource forensic tools include Prefetch Parser, available for download here.

PECmd.exe -d C:\Windows\Prefetch --csv c:\temp

A second file provides a simpler timeline:
