Hi, I am using Windows 7 Ultimate. Yesterday, I tried to delete a standard user account from my computer and now today when I try to boot my PC, the Windows 7 stuck at the welcome screen. I tried to boot into safe mode and create a new user with the same username as the one I deleted. Then, I reboot again. But I still can't get into both accounts. Windows 7 just stuck at welcome screen or with black screen and a mouse on there. Then, I try with startup repair. Windows 7 detect nothing problem, so the fix don't help at all. What can I do now to solve the problem? Thanks.
