True,

Take those lines and put them into a text file, then name it anything u want to as long as it ends in .bat that way u turn it into a batch file. Then you double click it and it will run. In order to run SFC, all you have to do is go to Start > Run then type in sfc /scannow and Enter. It should start to run, the only problem is that if files are missing, it may ask you for the XP cd that you no longer have. Try the batch file first. You can also copy and paste each of those lines (one at a time) into the Run box and execute them that way.
