I am not sure if WinNTSetup can do this, but thought I would ask. I have a Windows 7 x64 machine that I can log into in Safe Mode, but in the standard boot, I can't. I get to the logon screen and when I click the user icon it just flashes/flickers and returns to the user icon screen, no password prompt. The shutdown and accessability buttons work there. This happened after removing fingerprint reader software getting ready for W10 upgrade. I figure that did something irreversable. I wanted to do a repair install but unfortunately the standard Windows reinstall requires you to be in the standard desktop which is odd. Is it possible to do a re-install with WinNTSetup like the re-install from Desktop that will keep all my applications and other settings in tact but replace the system itself? Thanks.
