A:
Set the Checked property to True in the Properties window of Visual Studio at design time.

A:
For a given checkbox? Edit the form in the forms designer, and change the Checked
property to true.
For all checkboxes in the environment, without changing each individually? Can't be done. Though I suppose if you got really ambitious, you could write a post-compiler or some such.

A:
You haven't specified which platform, so I'll answer this for WPF, in which it's definitely possible.
You can use the OverrideMetadata method on CheckBox.IsCheckedProperty to provide a default value of "true" for all CheckBoxes. Add this code to your App class (in App.xaml.cs):
protected override void OnStartup(StartupEventArgs e)
{
base.OnStartup(e);
CheckBox.IsCheckedProperty.OverrideMetadata(typeof(CheckBox),
new FrameworkPropertyMetadata(true));
}
