My moms laptop is slow and old af,ofc no maintenance at all only browsing,face,shoping and shit there is no hope to clean it anymore so i decided to install some lightweight OS on it,curently it has windows 8 but i wanna lightweight as possible as this laptop is very crappy,its HP550 Intel Celeron 2 Ghz and 1gb ram. So whats best OS for this system,mainly for browsing,facebook,youtube ect.? tnx in advance.
