Windows Server 2016 prompts to specify an alternate source path when installing the IIS service

When installing IIS in Windows Server 2016, I encountered the following prompts

Open PowerShell and execute the following command

1. Set-ItemProperty -Path 'HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU' -Name UseWUServer -Value 0

2. Restart-Service -Name wuauserv

3. Install-WindowsFeature Net-Framework-Core

4. Set-ItemProperty -Path 'HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU' -Name UseWUServer -Value 1

5. Restart-Service -Name wuauserv

When the third command is executed, install the relevant software and wait patiently for the installation to complete.

When the installation is complete, the following prompt will appear
