I use a Toshiba Laptop with windows 10,..i also have an old computer of 12 years old a Dell Dimension 5150 which i find is still working as quick as the day i purchased it. Recently the Unofficial Version of Windows XP SP4 came out,..works great but took about an hour to download,..did anyone else try this out on the old Windows XP 2000.
