Win10 Spy Disabler is a free tool which helps you disable Windows technologies used to collect data and telemetry.
Launch the program and it displays a list of 20+ "privacy tweaks" you can apply, covering Windows 10, and more general operating system and application settings: "Disable Spying Services", "Disable Telemetry & Data Collection", "Always Send DoNotTrack on IE/ Edge", "Block Microsoft Telemetry Hosts", "Disable Recent Files, Folders, Docs, Progs", "Disable Windows Geolocation Service", "Prevent Wifi Sense from connecting to open hotspots", and more.
There's not a lot of fine control here. "Disable Cortana, WebSearch, BingSearch" is a single option, for instance: if you only want to disable one of those, you're out of luck.
Still, if you just want to turn off a lot of features in the minimum of time, Win10 Spy Disabler gets the job done better than most.
There's also a "System Tweaks" option which gives easy access to more general Windows settings: "Show Hidden and System Files", "Disable Windows Remote Assistance", "Disable Windows Update P2P Distribution" and more.
The package also includes a "Hide IP Address" button and "VPN Service" tab. These are just ads for a VPN service, but don't let that put you off - they're not intrusive, and if you don't click them, you can carry on using the rest of the program as normal.
