How to securely erase personal data from a used computer without affecting the software and apps? I am planning to acquire a used PC from a friend of my wife who wants to dispose of it. She asked me to wipe out her data before taking it, but I think she should do it herself for her own privacy and security. However, she seems to have no technical skills or knowledge. I am not interested in her data at all, but I want to keep the software and apps that are already installed on the PC. What is the best way to achieve this? https://technsight.com/
