It isn't that old, about 2 to 3 years, 4 max, it has Windows 7, it's an all in one Acer touchscreen pc with 1TB Hard Drive and 4GB RAM, i'm not sure of the processor ect cause i'm not home right now so i can't check, any ideas at least? Will it also slow me down in any way? I intend on upgrading the ram to run minecraft a little better, but i don't want a new OS to ruin that.
Added (1). I apologise, I meant Will my older pc be able to run windows 10 or at least Windows 8.1?
