I am still going to run the script. I dont think it could hurt considering the command isn't getting anywhere.

You could be right but I would be double checking it before continued use. I fail to see why a friendly script would want to be deleting that folder and it's an obvious bug in the script that is stopping it chewing away at an important part of Windows. There is also a possibility of other such functions which may work perfectly and delete things you need.

Such is the risk with any script that is not written by the end user.

Scripts written by third parties should only be used if the third party is verified by the community in general as a safe source of good scripts. The same, of course, applies to applications.
