Summary

Changed DataLossIndicator registry path from HKCU to HKLM and added PowerShell script for setting it with administrator permissions.

Security assessment

This change modifies the registry location for a client setting from user-level (HKCU) to machine-level (HKLM) and provides administrative script. This appears to be a configuration change for consistency or deployment purposes, not related to a security issue. No evidence of vulnerability remediation.
