Today I added a new Delphi project for a small issue I had yesterday: I reinstalled Windows 7 on my notebook Lenovo Thinkpad W500 (display resolution: 1920×1200) and Windows set the DPI of logon screen to 120dpi – I think that’s because of the high display resolution. But that is not the DPI I wanna see! So I wanted to change this, but there is no dialog where you can do that. But MSDN helped me: there is only one Registry value that is responsible for settings the logon screens DPI.
