如何从外部获取Powershell执行策略

Question

I need to find out the powershell (versions 4 and 5+) execution policy without using powershell itself

I tried to look into registry - HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\PowerShell

I found ExecutionPolicy value in two keys, HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\PowerShell\\1\\ShellIds\\Microsoft.PowerShell and HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\PowerShell\\1\\ShellIds\\ScriptedDiagnostics

The first one corresponded to the policy given by executing Get-ExecutionPolicy cmdlet, but on some servers in our environment the value is missing. Is there any other, 100% reliable, way to check the policy without using Powershell itself?

Answer 1

No key would equal Undefined

If the execution policy in all scopes is Undefined , the effective execution policy is Restricted , which is the default execution policy.
