Windows 7 black screen at welcome screen and doesn't show anything except the cursor after update service pack 1, i can Ctrl+Alt+Delete but unable to run task manager and anything . I've tried to unistall sp1 and my computer work normally but windows update auto install sp1 after i shutdown or restart, and my app need windows 7 service pack 1 to work. I can restore but windows update will install it again.
