The Team

The project was founded by Krutonium, though he hasn't done much on it in a while;
The project has been completely overhauled and revamped by Toyz, much to Krutoniums' delight;
The project has been helped immesely by ethanhs and darth62969, since Krutonium and Toyz are busy and bug reports take time;
The project is happy to have anyone who joins add themselves here;
The project is alive ;)


  • Very light colors makes the username and email hard to see. Be careful with lighter colors.
  • Some antivirus programs detect this as a virus, so turn it off (temporarily) before you start this program!
  • Requires Visual Studio 2015 Express for Desktop or better to open the .sln file.

In the event your login screen breaks, please fix it using this method and then report that it didn't work to us, along with the image you used, your computer specifications, and the version of the application. If you can also provide the broken .pri file, that will also be useful to us. Also any programs you have installed (like anti-virus, Stardock's ObjectDesktop, etc.) may be usefull. Thanks!

When You Experience Screen Flickers

Download Windows.UI.Logon.pri.bak.7z, extract the archive and put file Windows.UI.Logon.pri.bak to %WINDOWS%\SystemResources\Windows.UI.Logon. If the file exists, overwrite it.

Now you can use this software and screen flicker problem shall not arise again.

You can’t perform that action at this time.
