When I tried to use DISM last time with /Remove-ProvisionedAppxPackage, it froze and keep using ram, until it used all 8GB and then crashed. Maybe I screwed something in image?
Yes, it is a solution, but not very good one. I can only trim out features that were also present in WIndows 7 or vista. For example I don't need most of the preinstalled metro apps, but I cannot remove them with Win7/Vista apps.
Yeah, with Windows 8 for USB devices it meas that It's even more important to shrink your Win8 as much as possible. I hope there will be good solution out soon.
