If you have a password or multiple accounts setup with your Windows 7 computer, then you probably see your login screen multiple times per day. But the plain old Windows 7 login screen can get boring after a while.
Microsoft doesn’t provide an easy way to change your Windows login screen. Changing that screen requires you to either a) Edit registry entries or b) Download and install free third-party software.
If you’re like most PC users, you’d rather install a free program than edit important system files in your registry. So we’ll skip right ahead to the “install third-party software option.”
Note: If you want to change your Windows 7 login screen by editing the registry, you can follow the instructions to do that by clicking here.
