How to join Windows Insider plan?

As we all know, Microsoft has launched the Win10 Technology Preview system download, but downloading and using the Windows 10 preview system also requires registration to join the Windows Insider program. The registration process is very simple, starting with the Insider website. So how do you join the Windows Insider program? Below is the Windows Insider program registration process that I brought.
First Step: Go to the Windows Insider website, click on this link and log in to the Microsoft account.

Step 2: After clicking Join, confirm the agreement to the Privacy and License Agreement and click “Accept”Accept.

The jump is completed, indicating that the registration is successful.

You can then wait on the Win10 download page: http://windows.microsoft.com/zh-cn/windows/preview-download.
