Hi, I know it's very old laptop with dual core, 1 gb of ram ddr2, and integrated graphics, small hdd, but for some peoples it will be good, for browsing internet, watch movies online, listen music, check fb, and etc. simply tasks. I will think reinstall xp, but I see it have more and more problems, year by year, with support of browsers, antivirus, software, drivers, etc. So I wanna ask, what os will be lightest, and best for that old machine, support of drivers, and software? I don't wanna invest to extra ram, and ssd. I know it will improve performance, but don't know how much...
