per-user msi

About this tag
The per-user MSI tag covers a specific compatibility regression introduced by Microsoft's August 2025 cumulative updates, including KB5063878. These updates caused unexpected User Account Control (UAC) prompts and Windows Installer error 1730 for standard users attempting per-user MSI installations or self-repairs. The issue primarily affects non-administrator workflows in enterprise and lab environments, blocking applications like AutoCAD, Firefox, and SAP installers. Microsoft provided mitigations such as Known Issue Rollback (KIR) and operational guidance for IT administrators. Discussions focus on the balance between security hardening and operational compatibility, with emphasis on deployment strategies for large-scale Windows environments.
