Here are some "timeless" and lesser-known software tools that I find to be very handy for my daily computer/internet use.
Replaces default Calculator. Surprisingly useful scientific/graphing calculator.
Simple yet very powerful & fast file/folder search tool.
Provides quick & easy way to resize images from the right-click menu.
A feature-filled Notepad replacement for developers, i.e. syntax writing/reading, debugging etc.
A good, free compromise between MS Paint and Adobe Photoshop.
Easily converts almost any audio/video file to another format/size.
Website that extracts and downloadst online media from YouTube and such.
Software for storing & adding citations in essays/project/papers, this software (and its MS Word Add-in) is a must for any academic writer.
