I ran the app center live-update and it installed a load of stuff. Half of the stuff it tries to install are not even new versions and they fail. It also installs a load of hotfixes for Windows 8, I'm on Windows 10..
Along the way one of the broke my ethernet connection, uninstalling and reinstalling the bigfoot software and drivers, chipset drivers etc didn't fix it.
Had to totally uninstall the app center to get my internet back again!
How are W8 hotfixes even allowed to get installed on W10 I don't know. I'm not even sure if it was these of another one of the updates that broke it.
Think I'll stay away from the app center for a while as I don't really trust it anymore..
