Only couple things you may try.
1. cd \windows\system then run cmd.exe as administrator.
2. Check the ownership of these files. Make sure you have the right or the owner of these files.
If all fail,Google "Elevated Command Prompt". Some one has already created a short cut for cmd.exe. Maybe you have something you think you are doing but not. The property of this shortcut is already preset. If you still can't run sfc.exe then either you didn't follow the instruction exactly or something wrong with your system. Each person has his own preference to activate Windows, maybe yours are different.
