Win7/Win8.1 can not upgrade the official version of Win10 for free? How to upgrade free after the win10 free upgrade time?

However, according to the Reddit users of foreign forums, there are still regrets. In addition to users who use assistive technology, they can continue to enjoy the free upgrade of Win10. Ordinary users can continue to enjoy this benefit by using the “Time Backward” approach.

The premise of this method is that you have installed the Win10 free upgrade patch, and then you need to adjust the system time until July 30th.
This way, those upgrade tools that have already retired will be rejuvenated, help you download Windows 10 and remind you to install. After testing by foreign netizens, this method can not only successfully upgrade the installation, but also successfully activate.

It should be noted that after adjusting the time, remember to cancel the network time synchronization (as shown in the figure above), users who use the soft media time (click to download) should also cancel the synchronization in the settings (as shown below) ), otherwise it will not be long after the adjustment, the system time will return to normal, free upgrade will not play.

It can be seen that the "retirement date" set by Microsoft for the free activation tool is determined only by the user's computer time, and there is no synchronization server time. As long as the client sends the download request, the server will respond.
But this "vulnerability" is still difficult to determine for how long it may exist. Maybe Microsoft will block it soon, or Microsoft thinks it doesn't matter. After all, people who want to accept benefits have already started. N times.
The above is the solution that Win7/Win8.1 can't upgrade Win10 official version for free. It is here, and now I want to upgrade to win10 friends, try to see it!
