Answer 1

When you click restart from your app, make the following modifications to the registry:

Create an entry in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run registry branch.

Use

Registry.LocalMachine.CreateSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\YourAppName");

to create an entry.

And

RegistryKey myKey = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\YourAppName", true);

myKey.SetValue("YourAppName", "AppExecutablePath", RegistryValueKind.String);

to set the run path.

After the system has restarted, your app starts and removes the restart entry by calling this:

Registry.LocalMachine.DeleteSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\YourAppName");

Answer 2

It seems like your best bet would be to add your program to RunOnce, instead of Run. That way it will be started after the next reboot, but you won't have to worry about erasing the key afterwards.

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce

Answer 3

This is a better answer as you should not create a SubKey. Also this will automatically dispose.

string runKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Run";

using (RegistryKey key = Registry.LocalMachine.OpenSubKey(runKey, true))
{
    key.SetValue("MyProgram", @"C:\MyProgram.exe");
}
