To get the update go here and get the W10 media creation tool. When you run it you have two choices: Ugrade the PC directly over the Internet or Create an ISO file from which you can burn installation disks to use later. It only works on W7, W8 or 8.1, those on Vista have lucked out.
I haven done my Lenovo W8.1 netbook/tablet and my W7 laptop without any problems.
