I have just started using Powershell mainly because I need the ability to change affinity in a running program. Everything is set up correctly with a simple profile in MyDocuments/WindowsPowershell and I have used Set-ExecutionPolicy RemoteSigned. I have scripts in a separate folder in MyDocuments/Scripts and my Powershell shortcut on desktop opens Powershell in that folder. Up til now whenever I double clicked on a script it would open in notepad which was OK when I was editing the scripts but suddenly when I double click on a script it is actually running in Powershell. I prefer this as it saves me opening Powershell but just wondering what sort of behaviour would cause this to happen. The only odd thing I can think of is that I opened Take Command to see if I could run some PS commands from the TC console. After closing TC the behaviour is still persisting.
