Hey guys. I just got a laptop from one of my cousins to use for college that is running Windows 7. Since it was pretty slow I decided to do some things, including a disk optimization. When I clicked on “optimize disk” it told me to restart my system and once I did that my system rebooted with a black screen with white lines of text saying “2 percent completed. (020908 out of 378608 files processed)” and I can’t seem to do anything to get out of it. The problem is that it’s taking a really long time and I need to finish a paper. Is there a way to interrupt the process without damaging the hard drive?
