Un0wn_X wrote the batch automated code to replace sethc.exe (Sticky Keys) and utilman.exe (Utility Manager) into a cmd shell. This is valid for any windows operating system and can be easily executed during the windows login screen. On the windows login screen, you are under the NT AUTHORITY/SYSTEM account which means you have the highest privileges on a windows machine.
You can get a cmd shell by pressing the Shift Key 5 times or by pressing the Windows key + U or the blue color icon at the bottom.
Un0wn_X had an idea to write a Meterpreter script to make this easier for pen-testers. Un0wn_X and Hood3dRob1n wrote a Meterpreter script to support the Metasploit framework. This comes in handy when using RDPs and when at the login session you can easily trigger a command prompt.
