Open Source Software for Windows
Windows Sandbox
Windows Sandbox is a virtual machine application that lets you quickly spin up a virtual clean OS imaged from your system's current state so that you can test programs or files in a secure environment that's isolated from your main system.
TigerVNC
TigerVNC is a high-performance, cross-platform implementation of VNC (Virtual Network Computing). The TigerVNC client/server application allows you to launch and interact with graphical applications on remote machines over the internet or a local network. TigerVNC provides the levels of performance necessary to run 3D and video applications, and it attempts to maintain a common look and feel and re-use components, where possible, across the various platforms that it supports. TigerVNC also provides extensions for advanced authentication methods and TLS encryption.
TurboVNC
TurboVNC is a derivative of VNC (Virtual Network Computing) that is tuned to provide peak performance for 3D and video workloads. TurboVNC was originally a fork of TightVNC 1.3.x, and on the surface, the X server and Windows viewer still behave similarly to their parents. However, the current version of TurboVNC contains a much more modern X server code base (based on X.org 7.7) and a variety of other features and fixes not present in TightVNC, including a high-performance Java viewer. In addition, TurboVNC compresses 3D and video workloads significantly better than the “tightest” compression mode in TightVNC 1.3.x while using only typically 15-20% of the CPU time of the latter. Using non-default settings, TurboVNC can also match the best compression ratios produced by TightVNC 1.3.x for 2D workloads. Furthermore, TurboVNC contains some unique features that are designed specifically for visualization applications.
UltraVNC
UltraVNC is a powerful, easy to use and free remote desktop access software. The program allows you to use your mouse and keyboard to control the other PC remotely over internet or a network. Allowing you to work on a remote computer, as if you were sitting in front of it, right from your current location.
Apache Storm
Apache Storm makes it easy to reliably process unbounded streams of data for real-time processing. It is a distributed stream processing computation framework written predominantly in the programming language Clojure. The software is released free and open-source under the Apache License. In a nutshell, Apache Storm does to real-time processing, what Apache Hadoop did to bactch processing. Large corporations like Weather Channel, FullContact, Twitter, Yahoo, Spotify, and Alibaba use and trust Apache Storm for big data analytics with fault-tolerance and fast data processing.
Avant Browser
Avant Browser is an ultra-fast web browser designed for the modern web. It provides a user-friendly interface that brings a new level of clarity and efficiency to your browsing experience, and frequent upgrades have steadily improved its reliability.
Zim
Zim is a graphical text editor used to maintain a collection of wiki pages. Each page can contain links to other pages, simple formatting and images. Pages are stored in a folder structure, like in an outliner, and can have attachments. Creating a new page is as easy as linking to a nonexistent page.
ReverseSSH
ReverseSSH is a statically-linked ssh server with a reverse connection feature for simple yet powerful remote access. Most people find ReverseSSH useful during HackTheBox, CTF's and similar challenges.
EiffelStudio
EiffelStudio is an Integrated Development Environment that enable you to produce correct, reliable, maintainable software and control the development process. The IDE is specifically designed for the Eiffel programming lanaguge and comes with a debugger and browsable editor that makes it easy to navigate parts of your system and track down bugs, and quickly fix them.
