Microsoft seems to be preparing a more aggressive upgrade policy in Windows 10. While the new operating system first appeared as an optional update, it has since become recommended and available for download through Windows Update. 
However, in addition to what we already know, the company has recently made some changes to the older Windows 7 and 8.1 operating systems to make sure that more computers are upgraded, regardless of whether their owners want it or not.
The settings that were set to stop the upgrade to Windows 10 are reported to be reset from at least one of the updates released by Microsoft for Windows 7 and 8.1.
The specific information comes from the developer of GWX Control Panel, a application which was developed to prevent upgrading to Windows 10.
"Thanksgiving weekend I started receiving reports that the Windows Update 'AllowOSUpgrade' setting had changed on several computers, and it continues to give notifications at least once a day," says Josh Mayfield in ComputerWorld.
In other words, systems with Windows 7 and 8.1 can now easily upgrade to Windows 10, and there is no way to block automatic updates at this time.
Everything is naturally due to updates for older Windows systems, and according to Mayfield, it is the same update that is re-distributed again and again.
"Microsoft has released this update several times," Mayfield continued. "It doesn't change name of the informed versions, but in every release there are new binaries.”
