According to Windows 10 and Windows Server 2019 update history page, the company continues to pause Windows 10 version 1809 for some Intel platform users. The reason for the suspension is mainly that some Intel drivers still have problems. It may be abnormal to connect the display using HDMI/USB-C after the user updates.
The driver version is mainly Intel graphics driver 188.8.131.5244 and 184.108.40.20645, and subsequent issues have been fixed.
