I've had this laptop for over five years and it's really beginning to act its age, slowing down and what not. I have a lot of programs on it that were pre-installed when I got it which I have never used since then, but that I've been afraid to remove on my own for fear of disturbing the laptop's ability to function correctly. I've listed the ones I feel are completely useless. Can someone let me know which ones are safe to delete forever and which ones I need to keep? Thanks so much!
