Step 1: Understand Windows PowerShell script execution
PowerShell requires downloading the script file and then executing it explicitly.
Step 2: Analyze options
Invoke-WebRequest -Uri https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 -OutFile get-helm-3.ps1; .\get-helm-3.ps1 downloads the script and runs it correctly; Invoke-WebRequest -Uri https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | Invoke-Expression pipes raw content incorrectly; curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash uses bash which is not native to Windows PowerShell; choco install helm is a valid alternative but not the official script method.
Final Answer:
Invoke-WebRequest -Uri ... -OutFile get-helm-3.ps1; .\get-helm-3.ps1 -> Option A
