I got automatic Windows up date last night. After the updates, I can't do anything except turn on the computer, see the HP page, the green log in with password page, then all goes dark blue and freezes. It will not even rcognize the keyboard to back out. It is an HP Envy 20 all in one desktop. I have removed the back, all looks good, everything is secured and in place. I have no idea how to fix this and frankly am very disappointed that we are having this problem as the computer is still quite new.
