Here is a short list of software I use, love and recommend.
Bvckup 2 - Backup for Windows. Fast, simple, beautiful. I recommend it to both techies and non-techies. It is totally dead simple to use. I have it running on all computers in my close family. It is the iPhone of backup if you want.
Camtasia - Screen video recording The best screen recording software I know of. It doubles as a capture and editing tool. My screen recordings are all done with Camtasia.
Snagit - Screen capture Tony, CTO of a big financial company once remarked my emails are very well crafted, it is a pleasure to read them, I am a great communicator. He was referring to the images I included to make my point clear. Really, he was complimenting Snagit. Indeed it is a great, fast tool. Make a screenshot, draw on it, add to your mail, done.
Sublime Text - text and code editor Simple, fast, beautiful text/code editor. Enough said.
