    Sup there, I think your piece of command works quite well, and it does succeed. But the only thing is I could only get the first stage successed, after step 3. So, After step 3 its not working and the error still existed?? I dont know and not too sure how to continue on after checking the last step?? what do we do then?? restart the pc or what else?? Are there any other steps you might have similar to this one? or any other menthods to try and activate this?? Big thanks anyways. It was helpful but works half for mine, but the other half still existed!! error code 0X8007007B - this is shows!! after done all your steps and follows. what your other way or ideas??
