How do I run a PowerShell script even if Set-ExecutionPolicy is banned?

Question

The Set-ExecutionPolicy command of PowerShell is banned, so I can NOT run like this:

PS> .\script.ps1 (enter) 

Is there another way to run the PowerShell script except from the "Windows PowerShell ISE"?

PS: I was able to use Java's ProccessBuilder to run a single PowerShell command, but don't know how to run the whole script.

Answer 1

This is what we use to run PowerShell scripts from Java (works regardless of the execution policy):

powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile -WindowStyle Hidden -File <script_name> 

Answer 2

The easiest silliest way around this is just:

gc .\script.ps1 | iex 

This works in PowerShell and doesn't care about ExecutionPolicy. Just make sure that you are careful with newlines. Keep {}s and similar on the same line, using ;s where needed.
