My laptop is too slow in any work what i can do?

Always clean your disk space, and registry files, delete all the unnecessary files (music, video, word, photos) that you do not use or need. Try searching for your processor type, your RAM, your disk space and search over the internet and find out for yourself if you have reliable computer hardware, if you don't have then upgrade. Delete unused programs or remove window components that you don't need. Try limiting your start up programs for your computer to boot faster. Clean your disk space, you can clean your restore point if you think you don't need it because it really takes a very large disk space. If you really don't know much of computers as to how to boost it up, try using Tune Up Utilities, it can help you a lot! Cheers!
