Once a month or so I run AppSnap, a free tool that shows which of
the freeware tools on my PC need updating. AppSnap scans my system
and lists the apps, the version is on my PC, as well as the
program's current version number. I choose the programs needing
upgrading (or new programs I want to install) and click Upgrade.
AppSnap silently installs each app so I don't have to deal with
separate application installation routines. You can scan for
applications in various categories, such as Installed, Not
Installed, Upgradable, or, if you want to remove programs,
Removable. The big surprise was how many popular tools--and most of
my favorites--AppSnap had in its database: CCleaner, Firefox,
Google Desktop, Google Earth, iTunes, Opera, PDF Creator, Winamp,
and Thunderbird, to name just a few.
