WINDOWS FIRST FREE
This is the part that Microsoft has never thought of before. It's free. It is said that the OS will be provided as a service method (Window As A Service). I'm not sure, but I have to watch a little more, but it seems to be convenient to change the device to an upgrade rather than to initialize and reinstall the device. Not only will it save money and time, but it will be less stressful.

Existing Windows 7 and 8.1 and Windows Phone 8.1 users can upgrade for free for one year from July 29th. Once upgraded, you will have a permanent license. You can reinstall again and again. Of course, the same is true for newly purchased devices. However, Windows 7, 8.1 Enterprise, RT, etc. are excluded.

The funny thing is illegal users. All can be updated to Windows 10. Of course, it is said that illegality is not genuine and illegal status is maintained, so there are security problems such as malicious codes, e-commerce errors, and disclosure of personal information and some functional restrictions. https://www.indycrwindowskey.com/

If you are using Windows 7, 8, or 8.1 now, we recommend that you click the Windows logo at the far right of the taskbar to make a reservation. It's forgotten and there is a fear of overlooking the upgrade. It's a simple process, just by registering your email address. When the installation is ready, a notification window informs you.
