A past update for Powershell 2.0 and WinRm 2.0 was designated Optional. (Which I didn't download. Do I need this?) Had trouble with the recent Live Essentials update and after some reading uninstalled Windows Live from my system which re-designated the Live Essentials update from Important to Optional. Now I find that the Powershell/WinRm package has changed ftom Optional to Important. Any idea why and how I should proceed?
