Certain Windows updates in Windows 10 deliver extra "options" for telemetry on your machine. It is advisable to uninstall them:

For additional privacy, you can add these entries to your hosts file, which is located in:
C:\Windows\system32\drivers\etc

You can edit and save the file by opening Notepad as Administrator (Press Windows key ("flag" icon), in the search bar enter "notepad", right-click on notepad and choose Run as Administrator - then browse to the hosts file location).

Note: this does NOT block any Windows Updates.

Copy and paste the following below all the other text in there, save the file. That's all:
