How to correct this issue ? but with a problem for handicap person...
Just disable the sticky keys prompt from running when you press shift 5 times. Then when CMD is renamed to SETHC, it won't pop up. Solved.
Start > type "change how your keyboard works"
Click the first option
Click set up sticky keys
Uncheck turn on sticky keys when shift is pressed 5 times.
You really don't need to have a Windows disc or image on a USB either to make the exploit work. I'm trying to say that disabling the PC from starting from a different drive than the internal system drive won't prevent the exploit from being performed. This workaround is done by resetting the computer when it's starting up and using a startup repair to get access to the file system to rename CMD to SETHC. Sure, it's hard on the disk drive, but if you're breaking into somebody else's machine, you don't really care.
