About this tag
The msi advertising tag on WindowsForum.com covers discussions about Microsoft's Windows Installer (MSI) hardening changes introduced in the August 2025 cumulative updates, particularly KB5063878. These updates address CVE-2025-50173, a security vulnerability, but have caused compatibility issues such as unexpected UAC elevation prompts and MSI Error 1730 for non-administrator users. Topics include the impact on MSI self-repair flows, per-user installs, and temporary mitigations like Known Issue Rollback (KIR) and administrative workarounds. The tag focuses on the intersection of security hardening, Windows updates, and enterprise IT management.
