Sure, I understand. You're experiencing issues with your login and Ctrl+Alt+Delete screens, and you've already tried running the repair command. The problem seems to be with the Windows UI logon DLL being corrupted. You might want to try reinstalling the Windows Update or using System Restore to recover from the issue.
Access the command prompt via advanced boot settings in Windows. Execute these commands one at a time. Some scans may require time to complete. Enter DISM /Online /Cleanup-Image /RestoreHealth. Press Enter. Run sfc /scannow. Hit Enter again. Proceed with chkdsk /v /f /r C: when prompted. Choose to schedule at your convenience. If the issue persists, consider backing up your files.
