User Comments

It comes with Paperport, PDF Converter and PowerPDF as standard. They are normal scanning apps that output direct to PDF. NuanceWDS is a process that enables Windows Desktop Search to index PDF contents. WDS only indexes the names of PDF files if NuanceWDS is disabled. It can be very resource hungry - 25% of CPU cycles, so I disable during the day and enable it to index overnight.
WDNuance - monitors your use and nags if there is anew version - every time the progran thinks that there is a new version it becomes extremely intrusive - at one point I was seriously thinking of uninstalling the program - then I removed WDNuance and it stopped nagging me
