Overview

• The August security update (KB5063878) enforces admin credential prompts for Windows Installer repair operations, causing unexpected UAC pop-ups for standard users.
• Microsoft lists widespread impact across supported Windows 10 and 11 releases and many Windows Server versions, with failures in per‑user installs and silent MSI repairs.
• Affected scenarios include MSI repair commands, Active Setup flows, Configuration Manager advertising, and some Autodesk launches, with Office Professional Plus 2010 failing with Error 1730 for standard users.
• Microsoft advises running affected apps as administrator or using a Known Issue Rollback Group Policy for select builds after contacting business support.
• A forthcoming Windows update will let IT admins permit specific apps to perform MSI repairs without UAC prompts, while Microsoft also investigates NDI streaming issues and reports no link to SSD or HDD corruption.
