Never 10 is an easy to use utility which gives users control over whether their Windows 7 or 8.1 will upgrade itself to Windows 10. The name "Never 10" is a bit of an overstatement, since this utility may also be used to easily re-enable Windows operating system automatic upgrading. But the primary reason for using this is to disable Windows' pestering insistence upon upgrading Windows 7 or 8.1 to Windows 10.
