Recently I had to work with Powershell on a windows XP machine and I was wondering how to to set this up.I had never worked with Powershell on XP and was curious on how to configure it.
I was able to find a KB article for Windows Management Framework which included Powershell 2.0
http://support.microsoft.com/kb/968929
I was able to find the correct product and downloaded the same.
The install went smooth and a reboot was not forced.I was back running with powershell on windows XP again.
Thanks for reading.
