Windows Sandbox is a powerful feature in Windows 10 that allows you to run applications in a secure, isolated environment. By customizing its settings, you can optimize performance, allocate resources, or enable specific features to better suit your needs. Whether you’re a developer testing software or a user wanting a safer browsing experience, changing Windows Sandbox settings can enhance your workflow and security.
