I deleted Windows Security and then rebooted. Still haven't seen much difference in performance. I do see that there are 3 drives on here all with files in them and some files I'm not sure what they are. I really don't know why I would need so many drives. I know I need the c:\ drive and the drive for the cd/dvd drive but there is a d:\ drive labeled Download, and e:\ drive labeled CD/DVD with files in it. Can I move these files and delete these drives or should I leave the drives? If I leave the drives how should I utilize them for the max performance of the computer?
