So win7/win8.1 free upgrade after win10 still have to pay every year? Some netizens raised this question

Some netizens asked on Twitter: "Your company needs to clear a year free upgrade to the end What does it mean, does it mean that you need to pay an annual fee?

In this regard, Gabe Aul, the head of Microsoft Windows Insider project, replied:
“Please allow me to close the door for you: (Upgrade After that) Win10 will not take an annual payment method. ”
According to Microsoft's announced plan, the first year after the official release of Win10, from July 29, 2015 to July 29, 2016, if you are using Windows7/Windows 8.1 Genuine system, you will be able to upgrade to Win10 for free, and you will get a permanent free update after the upgrade. After one year, if you want to upgrade Win10, you will need to pay a certain fee. According to the current news, Win10 is the same price as Win8. However, Microsoft may also offer certain offers to attract older system users to upgrade to Win10. In short, the usage fee will not be charged annually after July 2016.
The cause of user confusion may be Microsoft's claim that "Win10 is service", which allows users to assume that Win10 will subscribe by way. In fact, Win10 is a service representative on behalf of Microsoft will take a faster update frequency for Win10 to launch a feature update to replace the previous SP major update package.
< All eligible devices, after upgrading to Win10, we will continue to provide updates throughout the life of the device, keep the device in a safe state, and continue to provide new feature updates, all free of charge. . ” Microsoft stressed.
