Creator's update installed automatically today, as soon as it completed I uninstalled it as I had no desire for the new features. Upon restarting after the uninstall, no default Windows features function or display properly, I cannot alt tab or I get a black screen, I cannot open programs to troubleshoot because the admin confirm Window cannot display. Control panel gives a "no associated program" error. Only third party apps function if I can get to them. I cannot properly troubleshoot in safe mode either due to the limits of it but I functions normally there. Have been trying to fix this all morning but I am at a loss, I had to type this on a phone so apologies for any bad composition
