Free software app, dubbed DoNotSpy10, allows you to disable a total of 37 Windows 10 privacy issues with just one click. The app makes changes in the Registry in the background, so you need to reboot the system once for changes to take effect. Windows 10 sends all the gathered data back to Microsoft so that the data can be used by the company for personalisation and targeted ads. The free app prevents you from going through dozens of features settings in Windows 10 and lets you adjust all privacy and security settings in one place with just a click.
