SharePoint 2010 does not support PowerShell 3.0 at this time. If you or your admin team install PS 3.0 on your SharePoint 2010 farm, you will have some compatibility issues with the SharePoint 2010 Management Shell. This happens, because the shortcut to start the management shell generically targets the most recent version of PS installed, not 2.0. If you believe you are having this issue you will likely see an error similar to the one below.
