Point to determine whether or canceled automatically restart, please pointers on how to solve! ! Thank you,

because whether OK or Cancel, Winlogon will eventually quit, which led directly to windows crash.You can try to copy from another computer, a Winlogon replacement, but not necessarily helpful.In this case, it is recommended to do System Restore ( If you have backed up), or reinstall.
