Never 10 Tool

If you are tired of being reminded to upgrade to Windows 10 - and you don't plan on upgrading to one of Microsoft's best OS's ever, you can give Steve Gibson's Never 10 tool a try. The beauty is that this tool is exactly that - a tool. It doesn't have to be installed on your system - just ran. Once the system has been modified, the program can be deleted. If you do decide you want the free upgrade to Windows 10 however, remember that the free offer expires on July 29.

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, at least initially, disable Windows' insistence upon upgrading Windows 7 or 8.1 to Windows 10.
