So I got my Mom's old laptop from like 2012 or something. I was expecting 2 gigs of ram and a Pentium piece of garbage. I was pleasantly surprised to find 4 gigs of ram and an i3 2330m running on windows 7. shockingly it's running better than my $400 school-issued Chromebook with a celeron n4020. Anyways I'm considering upgrading to windows 10 but I don't want to cripple performance. I'm not good with software and that stuff so Im scared to test it. Think I should upgrade it to windows 10 or no? If yes does anyone know a way to do this without external storage?
