A few examples that you can't normally uninstall are Cortana (" Windows Search "), Camera, Alarms/Clock, Email/Calendar, Movies/TV, Pictures, Photos, 3D, Voice recorder, Groove Music, Maps, Messages, One Note, Paint 3D, People, Sticky Notes, Xbox, Xbox Game Speech.

You can certainly remove some of them manually or using 3rd party solutions but something eventually goes wrong specially after an update. I mean I can remove most of the executables from the Windows folder, my point is that it's going to break something eventually. Removing Cortana and SearchUI used to work before AU, now it just freezes my start menu completely.

I'd like to completely remove Cortana, or at the very least completely cut it off from any kind of internet access. I got it mostly hidden and voice access disabled, at least.
