Seems like you can do this without powershell_out – you can coerce powershell to return an exit code using the exit command in powershell – here’s an example:
not_if 'powershell -noninteractive -noprofile -command "exit [int32]((Get-ExecutionPolicy) -eq 'RemoteSigned')"'
The above guard will cause the resource to not execute if powershell’s execution policy is set to remotesigned.
Somewhat related, here is a proposal to make it easier to use powershell and other script resources in guard expressions:

Chef resources do not return a value (as far as I know). You will have to use “powershell_out” to check for certain condition and based on what it returns you can trigger the iis_config resource.

Can I use powershell to check the settings, but if the powershell indicates they are different than what they should be, have the iis cookbook sections run again?
Something like
powershell_script "checking setting #1"
(check if settings are the same)
iis_config
only do this is "checking setting #1" returned false.
This is more of a capability/syntax question.

I ran into same issue when I started using IIS cookbook. I had to write my own cookbook with powershell script in it to do the job.I used guards to ensure idempotency.

How are (those of you who are working in Windows/IIS), ensuring Idempotent Recipes for configuring IIS?
On occasions where the community cookbook doesn't provide idempotent resources, I call out to powershell, and add a guard where needed.
