Removing Windows Optional Feature In Win8

Hi All,

I have a Windows 8 (not 8.1) laptop with an SSD that's constantly almost out of space.  Disk cleanup goes some way, but I dug around and discovered the removing Windows Optional Features.  However, I'm trying to pin it down to either "IIS" stuff or anything disabled.

Attempting this just throws an error:

Disable-WindowsOptionalFeature -Online - Remove | ? featurename -like 'iis*'

Same with pulling a list via "disabled" status.

Any ideas on how I might get at it?  The above works for pulling out a list of "iis" items, which I don't need, but not for "-remove".
