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.
But why should I change the Registry by hand? And hey, I never done something with the Registry so far! So I decided to create a small tool which allows you to change the DPI of the logon screen within some seconds. Start the application, give it administrative rights, click on the wished DPI option and apply it. It can be so easy ;)
