POSSIBLE DAMAGE DOES INCLUDE BUT IS NOT LIMITED TO DAMAGE ON OTHER APPLICATIONS, HARDWARE DAMAGE (OVERHEATING) AND DATA LOSS QuantumAccelerator is a free and open source application to easily manage Windows 10/11 in one place. With this application, I want to allow less tech experienced people to be able to manage their computer, especially when it comes to privacy. It isn't made with only less tech experienced people in mind, it accelerates the process of managing the operating system for everyone, and more advanced features will be added later. Managing files and privacy settings is heavily trust based and in my opinion should be available to everyone. That's why this application is completely free and open source.
