Resolving Error 0x800f0950 During Role and Feature Installation on Windows Server 2019

Follow these essential steps to address the error code 0x800f0950 while setting up roles and features in Windows Server 2019:

1. Update your system: Ensure your server has the most recent updates and patches. Navigate to Settings > Update & Security > Windows Update and select Check for updates.
2. Utilise DISM: Launch Command Prompt with administrative rights and execute the command: DISM /Online /Cleanup-Image /RestoreHealth. This command helps fix any corrupt system files that might be causing the issue.
3. Verify source files: Confirm that the source files needed for the roles and features installation are both available and accessible. If installing from a network share, ensure the share is reachable and that you possess the required permissions.
4. Temporarily disable antivirus: Occasionally, antivirus software may disrupt the installation process. Temporarily turning off your antivirus may allow the installation to proceed successfully.
5. Opt for Server Manager: Rather than employing PowerShell or DISM for installation, consider using the Server Manager. Open Server Manager, choose the server for installation, select Add roles and features, and follow the provided wizard to complete the process.
