You need to use the 'command prompt' in order to work. Just click the link holyness provided and follow the instructions.
Oh one more thing, don't forget to run the 'command prompt' as a administrator.
You should see: C:\Windows\System32
Type cd.. 2x and you should see C:\
Once that is done you type "cd Users" and then type "cd (your computer name)"
From there just type the commands from the instructions
