PowerShell v3 Invoke-WebRequest: Troubles with forms

Question

Since I upgraded to Windows 8 a lot of my PowerShell scripts relying on launching an invisible IE won’t quite work anymore, so I tried switching to the Invoke-WebRequest

Answer 1

To address your problem with the unsigned/untrusted certificate, add the line

[System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}

before the Invoke-WebRequest statement
