The PCs aren’t really converted. My local PC is XP, but the new VM I’m on is Windows 7, and I just copied over as many settings as possible. Most people do just double click the batches, which works fine, but there are two people (myself included) that tend to create the batches, and it’s more convenient to be able to do the testing with a shortcut from within Notepad++ rather than having to go back to the folder and double click the batch between each change. If the batch doesn’t need to be edited before running then we always are just double clicking the batch, but some also have variables that we need to set before running.
I did end up finding the solution on another site though! I ended up needing to run Set-ExecutionPolicy RemoteSigned from both C:\Windows\system32\cmd.exe and C:\Windows\SysWOW64\cmd.exe and then everything work correctly. I appreciate the replies to try to help me figure this out.
