Free Powershell debugging tools

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 st开发者_运维知识库ep 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.

There's also the new Editor on the block, PowerSE

Since your question of june there were few changes. The actual PowerGUI script editor (version 3.0.0) doesn't work with PowerShell V1.0. But you can use a version before 2.0 . I'am using PowerGUI 1.9.5.966 which works perfectly with PowerShel V1.0. I give you a copy.
