Fix Windows Update Error 0xc1900223
Error 0xc1900223 can occur when you try to update your Windows 10 installation, especially when you install a feature update such as v1903 or v1909. There is no advice from Microsoft regarding this error.
According to Microsoft, the 0xc1900223 error indicates that there was a problem downloading and installing the selected update. Windows Update will try again later, and you don’t have to do anything for now.
Error 0xc1900223 may occur if your computer fails to connect to Microsoft Update servers or its content delivery network. This can happen if you have previously blocked a number of Microsoft server addresses manually or by using a special program that writes to the Windows HOSTS file. This error can also occur if you use a specialized DNS server to block third-party web addresses.
