Hi,
Since Windows 10, version 1803 have reached the end of service on November 12, 2019 and no longer receive security updates after November 12, 2019.
When a Windows 10 device is at or near the end of service, Windows Update will automatically initiate a feature update to ensure device security and ecosystem health.
The fastest way to get the upgrade is through Media creation tool or ISO file.
Please download Media Creation Tool from the link below and select Upgrade this PC at the first screen:
https://www.microsoft.com/en-us/software-download/windows10
This will save your files and apps while bringing you up to the latest version by the most stable method. It will also bring all of your Updates current and solve most problems since it reinstalls Windows.
Hope above information can help you.
