Windows blocks the execution of remote signed PowerShell scripts by default. If your execution policy still has this setting, you might see this error message:

C:\Users\test-user\Downloads\Install.ps1 is not digitally signed. You cannot run this script on the current system. For more
information about running scripts and setting execution policy, see about_Execution_Policies at
