PortableApps means portable apps for your PC, surprisingly
We've all dealt with IT Nazis at one point or another - those highly-strung individuals who demand every PC in the company is configured identically, regardless of its use, restricting you from downloading the apps and software you need to go about doing your job properly. They don't have the corporate responsibilities or love of TweetDeck you do, they'll never understand.
Here's a possible way around the issue; PortableApps is an open-source platform you can run from a USB flash drive. It has a fully integrated menu with a full suite of programmes ready to use, but you can add your own apps to it - instead of downloading programmes to your PC, you can run them straight from the flash drive. You can also save the likes of bookmarks, calendar settings and emails too.
You can download PortableApps for free without advertising, 30 day trials or signing up to spam for the rest of your days on Earth.
