From Optional to Important

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?

Thanks.

Windows PowerShell is a new Windows command-line shell designed especially for system administrators. The Windows PowerShell includes an interactive prompt and a scripting environment that can be used independently or in combination.

Do you need it?

I think you can just right click on it and select hide.

I don't need it, but I wanted to know why it became Important when it had always been Optional. Is it simply a glitch?

Thanks
