Maybe so - but I have no idea what. I am very conservative about what apps I add, setup changes I make to my machine etc. basically, if I don't plan to use an app, feature, or configuration every day, I don't install it. I can count on less than two hands the changes I made to my VM after install: MS Office 2003 Minitab 15 statistical program Bonjour for Windows Kaspersky Internet Security Brother Printer driver install Epson Printer and scanner driver install Shared external folder (firewire drive) That's it! So my machine is as close to "factory settings" as you can get.
