YOU CAN TRY REPLACING THE FILE IN QUESTION BY USING ANOTHER COMPUTER BUT IF YOUR GETTING THIS ERROR DUE TO WINDOWS NOT BEING SHUT DOWN PROPERLY THEN YOUR FILE HAS BEEN LOST THE FASTEST AND EASIEST IS A REINSTALL OF WINDOWS THERE IS A 65 PERCENT SUCCESS RATE ON REPAIRING WINDOWS MANUALLY BUT HOURS OF RESEARCHES AND TROUBLE SHOOTING ITS UP TO YOU IF YOUR WILLING AND IF YOU CAN DO SUCH REPAIRS WHEN YOU RELOAD WINDOWS IT RELOADS EVERYTHING ELSE YOUR PROGRAMS WILL NOT WORK AND GOT TO KEEP IN MIND WHEN YOUR SYSTEM WENT DOWN THE WINDOWS YOU HAD WAS NOT THE SAME SINCE YOU GOT IT OUT OF THE BOX THEIR IS HOTFIXIS PATCHES UPDATES THAT EFFECT THE ORIGINAL INSTALL SO YOU WILL NEVER GET IT BACK TO WHAT IT WAS DUE TO THOSE FACTORS! IF YOUR DATA IS IMPORTANT YOU MUST USE ANOTHER COMPUTER AND AD YOUR DRIVE AS A SLAVE AND PULL YOUR DATA OUT ONCE THAT IS DONE FORMAT YOUR PARTITION AND START FRESH THEN PUTT YOUR DATA BACK IN INTO THE FRESH INSTALL GOOD LUCK GUY ON THIS ONE BECAUSE I DO IT ALL THE TIME ITS MY JOB!
