PR Summary

This is a Windows platform issue only.

When running remote initialization script, the script block is considered internal and marked as trusted. In system lock down mode, PowerShell runs in ConstrainedLanguage mode and won't allow a trusted script block to run in the default scope.

Fix is to mark the initialization script as untrusted external when system is locked down.

Repro:

# PowerShell running in locked down system
Start-Job -InitializationScript { function Hello { "Hello" } } -ScriptBlock { Hello } | Wait-Job | Receive-Job

# Result
Error: "Cannot dot-source this command because it was defined in a different language mode. To invoke this command without importing its contents, omit the '.' operator."

Fix is to mark initialization script as untrusted "external origin" when system is in lock down mode, so that it can run in ConstrainedLanguage session scope.
