In order to experience Windows 10, it is hard, just see the dawn, but into endless darkness.
was originally enrolled in the Windows membership program. Because it is a preview version, a lot of bugs. We do as mice, almost every day to do the system. Good luck, a few days to do, bad luck, sometimes a day to do several times.
When Windows 10 was officially released, the hard work finally paid off, and after an upgrade, it was discovered that the system was Windows 10 Pro and was permanently activated. According to Microsoft, once activated, the computer's data is stored in the Microsoft database, the next time you reload the system, you do not have to activate the key. Unfortunately, the system crashed for a few days. Because Microsoft said, the reload system does not use the key to activate, so I foolishly re-installed. Oh, hehe, loaded found how can not be activated.
But it doesn't matter, I also have genuine windows7, can also book Microsoft's free upgrade program. So I loaded windows 7. After the patch, I saw the cute Windows icon.
Click on the Reservation. Then there is the long wait. After two days, I called Microsoft Customer service. If you've clicked on a reservation, your computer has already joined the free upgrade program, says customer service. Then you can now download the WINDOWS10 ISO file and install it yourself. It is then automatically activated. So, I believe the customer service sister, the system tray, made a new WINDOWS10 Professional Edition. Then, there was no then. As you should have guessed, I went back to Windows 7 and waited patiently for upgrade notifications.
