Have to do Windows Cleanup

Couple of days ago, I don’t have the guts to do online stuff. The laptop I am using is having dilemma already. Well, this laptop is already 5 years old so I should not be surprised and I don’t clean it regularly. I noticed this laptop is getting slower and slower everyday making me feel upset. I’m thinking of buying personal computer or laptop but I don’t have enough money. I have to think of other ways to solve my laptop problems. My brother who has computer shop told me about Windows cleanup. He said regular cleaning can make a big change and can longer the life of computers. I have to take his advice and call him right away after doing my online stuff. I know how to use laptop or PC but I have no knowledge in dealing computer problems so I have to ask for his assistance.
