I Got The Algorithm From http://www.catch22.net/tuts/selfdel.There Is Source Code In C++.
It works Like That.
- Execute Original File(First.exe)
- First.exe Copy Second.exe Into Temporary Directory.

Add The File suicide.exe in Suicide Project.
Now Right Click To Open selfdel.exe
properties.

Rest Of Things You Will Learn From Its Source Code

How It Works:
When You Start Suicide.exe
It Will Create The selfdel.exe In [AppDataLocalTEMP] Directory
Write Its Current Path To Registry.
Execute The seldel.exe And Exit.
Now selfdel.exe Get The Suicide.exe Path From Registry.
Delete RegistryKey.
