Not being that creative most of my free software apps are computer utilities but I’d love to contribute.

Keepass - Free, open source, light-weight and easy-to-use password manager. I use this every single day as it auto enters username and password for webpages, generates passwords, ridiculous encryption and it even encrypts your data in memory. Tiny and and no install.

IrfanView - Image viewer, fast cropper, re-sizer, paint functionality. Tiny app, no install.

VLC Media Player - Free and open source cross-platform multimedia player and framework that plays most multimedia files as well as DVD, Audio CD, VCD, and various streaming protocols.
