The PortableApps store offers more than 300 apps and they are all free and legal to use, installable by a single click (though sometime it can take a couple of attempts to get a connection to the store), and will be automatically updated. Application categories include accessibility tools, development tools, educational software, games, productivity apps, media development and editing tools, Internet tools ... it's an incredible list that includes many of my favorite Windows utilities such as FileZilla (a great FTP client and server), WinMTR (a ping and traceroute tool I'll cover next week) and Process Explorer (a Windows system tool).
I've found that PortableApps makes a great emergency toolkit for PC and Internet diagnostics and I've run it without any problems from local subdirectories, USB drives and Google Drive. If you use Windows, this is a great tool you'll find all sorts of uses for, so PortableApps gets a Gearhead rating of 4.5 out of 5.
