I have just bought a secondary refurbished Windows 7 laptop, mainly for when all my 4 grandkids are here. It only has 250GB of space and 4MB memory, they love to play Minecraft against each other so how much space is still good for them to play? I don't plan on loading anything that is not necessary to keep it trim but I've just done all the Windows upgrades and it's already at 197GB. Is that enough? I must say I'm very impressed with this laptop, its faster loading than my original that has 750GB and 12MB memory. I don't get it!! Thanks for any help offered.
