How did the Win7 system not receive Win10 push?

First, change the system update settings

1. Right click on my computer and select [Properties] to enter the Windows operating system.

2. Click [Windows Update] → [Change Settings] in the lower left corner to check whether the Windows installation method is automatic check and update.

3. After entering the change settings interface, find the [Important Updates] column. As shown in the figure, I don't know when to set the system detection update to [never check for updates], which is probably the cause of the failure to receive the win10 upgrade push notification.

4, reset the important update to [automatically install update], click [OK].
