After downloading and installing AuthUX, open the folder you installed AuthUX in, and open 'AuthUX.dll' with 'ResourceHacker.exe'. Click on 'Action', click 'Add from a Resource File', then select 'AuthUX.res'. Click 'Overwrite', click 'Check/Uncheck All', then click 'Import'. Now click on 'File', then click 'Save'. If done correctly, AuthUX should mimic the Windows Vista logon screen instead of the Windows 7 logon screen.
