Useful Programs/Software
There was a thread like this a few years ago, with some excellent contributions in various software categories. I think it might have been created by Del/Jason, back when he was a regular here.
Anyway, I think we should try and get another one going, as the old one necro'd long ago.
VirtualDub - A freeware piece of video software with a decent amount of features and plugins available. I use it primarily, nowadays, for basic video editing; and, despite having a GUI which some may find somewhat daunting, it's a great program once you start to learn your way around it. I've used VirtualDub for many years now, though it hasn't been updated in quite some time (late 2013).

Handbrake - Another free piece of video software used for video conversion and encoding. I've used it, once again, for years and find it to be a pretty decent option when it comes to video editing and processing when used in tandem with VirtualDub.

LibreOffice - A full office software suite, and a free alternative to Microsoft Office. It supports the proprietary file extensions of MS office, and receives regular updates from its open source community. Personally, I find LibreOffice to have a nicer UI than the newer versions of MS office; more reminiscent of MS Office 2003, back in the XP days.

Malwarebytes Anti-Malware - A pretty obvious one, and a security program that I have have used for many years now. I personally only use the free version, but I find it to be more than adequate for my needs. MBAM has been a staple app used in the de-bricking of many a family and friends' systems over the years.

I would also recommend an AV program, but it really is a matter of personal preference. I personally use avast! at the moment, after recently uninstalling Microsoft Security Essentials.
So, there's 4 free programs that I generally acquire shortly after a fresh install of Windows. Just personal recommendations of my own, but it'd be interesting to see what others have to add.
