thanks arthos. you don't know how you have helped me. I'm so grateful for finding this video. I had a virus on my laptop, i followed your instructions and my laptop is back to normal and even faster.
this is true! check disk was ported from windows 98 to the newer ones, and it still works! i used to have hard drive corruption but i ran this and some sfc /scannow and my pc was perfectly fine! ty for making a real tech video instead of telling them to delete system32 or something
