O&O Shutup is a good anti-telemetry tool for Windows 10, it has visual icon whether it's recommended to disable or not.
Be aware enabling all options may render some features unusable. For ex: "Please contact your administrator".
I recommend to not use these tools immediately and wait for the system to download any pending updates to avoid possibility of system corruption.
Windows 10 Anniversary Update has a planned release for August, 2nd.
If you (and many others) are paranoid about Cortana and personalisation features, you can disable them in the Settings > Privacy. Simply toggle off, just like any smartphone OS (ie. iOS and Android). It's not complicated to disable access to devices.
If you (or plan to) have multiple computers running Windows 10 on YOUR home network, you can use your current PCs bandwidth to upload the updates to YOUR other computers.
I recommend using 'PCs on my local network' only and you can find out how here,

Edit: Look up Black Viper for Windows and as advised do
not use msconfig.
