We love portable applications. You know, the kind that you can run from a single executable file without installing them to your computer. There's no need to uninstall portable applications you're not using. You can just delete them. And they don't make crazy changes to your Windows registry. Best of all, you can run them from removable media like a USB flash drive.

There a couple of great resource for portable applications, including the Portable Freeware Collection, which maintains a good list of applications and PortableApps, which not only has a list of programs that you can run from a Flash drive, but a nifty application launcher for your portable programs.

Like PortableApps, winPenPack offers a bundle of portable applications and a handy program launcher. There are several different winPenPack bundles available, ranging from an Essentials pack which weighs about takes up a few hundred MB to a 1GB version which packs a whole boatload of software. The Essentials pack still has a lot of great software including Firefox, Thunderbird, Filezilla, Gimp, Kompozer, and Pidgin.
There are also special versions labeled "school," and "games" that come with more specialized applications. When you first run winPenPack you'll notice that most of the menus are in Italian, even if you manage to find the option to change the language to English. But you can also download a 44MB ZIP language pack. Once you unpack that file to your installation directory your menus should appear in English.
