Windows 10, like any other operating system, allows certain websites to access personal information on your computer. It’s not that Microsoft wants to hack into your system or damage your computer. Rather, it wants to give you a better surfing experience. That’s why many websites allow you to extract information from your computer in exchange for relevant and interesting content. In addition, Microsoft does not hide this feature and allows you to disable it if you encounter any security threats.
