Quest Power GUI Script Editor is a nice free tool for writing and debugging Powershell script.
We have Windows XP SP2. Is there any similar debugger that let’s you debug step through scriptthat is provided free of charge by Microsoft that works on XP? I suspect that it’ll be easier to get a MS add on tool approved than a 3rd party.
Build-in Windows PowerShell ISE (GUI for Powershell) has debugging support.
