Hi Marty,
Thank you for your question.
Unfortunately, we are unable to provide direct download links for specific Windows ISO files through the Microsoft Q&A forum.
If your goal is to repair your current Windows installation while keeping your installed applications, personal files, and settings, I recommend following the steps in the Microsoft Support article below: Fix issues by reinstalling the current version of Windows.
This feature reinstalls the current version of Windows already installed on your PC and is specifically designed to repair system files and Windows components while preserving your data.
Best regards.
