Added
feat:NewRelic Infrastructure Agent Least Privileged Service Account Support on Windows (#2152)
This release introduces comprehensive support for running the Infrastructure agent under least-privileged service accounts on Windows:
Upgrade preserves service account: On upgrade, the installer now detects and preserves the existing service logon account (for example, a custom domain or gMSA account) instead of resetting it to LocalSystem. Permissions on the app data directory are automatically re-granted to the preserved account.
Fresh install uses
LocalSystemby default: New installations continue to register the service underLocalSystem. Useset-service-account.ps1(new companion script) post-install to switch to a least privileged account. Supports local accounts, standard domain accounts and Group Managed Service Accounts (gMSA). Also supports the credentials stored in Windows Credential Manager.Rollback safety: A marker file is written before service creation so the MSI rollback action only removes services created by the current run — it won't delete a pre-existing service during a failed upgrade.
Debug logging: Installation now writes a timestamped debug log (
newrelic_installer_debug.log) making troubleshooting easier.Impact: No breaking changes for existing installations using the default SYSTEM account. The new parameters are fully optional.
