PortableApps.com v14.2 released!
If you haven't heard of PortableApps.com yet, I highly suggest you check it out.
You can put many of your favourite programs on a USB stick to save your settings and take them with you, or just to save space on your main hard drive. :D
All free, and "legit".
My favourite apps to use are Thunderbird, Cyberfox, OBS, GIMP, 7-Zip, KeePassX, GPG, CCleaner, LibreOffice, and KiTTY (a suped-up version of PuTTY, an SSH client).
That looks like something I might use. I have 6 different computers that I use throughout the workday, I'm Downloading it right now.
