Oh no...
Although
http://download.sysinternals.com/Fil...ogonSource.zip still contains the original sysinternal version,
http://download.sysinternals.com/Files/Autologon.zip is already changed to the microsoft version... This means that my previously suggested trick may not work for all files...
I hope my trick can help us to recover all the source files.
Another thing:
1.
http://www.sysinternals.com/Utilities/Autologon.html
2.
http://www.sysinternals.com/autologon.html
Link #1 will redirect you to microsoft, but link #2 will not. It is quite helpful that sysinternal's url are well-designed and predictable.
