I'm not going to sit here and tell you the world will end if you don't go Win 10 yesterday(you'll get plenty from that camp as it is). If you know what your doing, only you know, and you are geek and security savvy and stay off line after LAST security update then press. I'm still rocking a WIN XP laptop, as well as multiple VMs with various WIN XP and WIN 7 pro configs

having said all that: If that's the way you want to go - DOWNLOAD ALL applicable updates NOW and SAVE them OFF onto other media (e.g., USB drives)

there is a lot to go through depending on your config. I would also tell you to try and start with "SP2" not SP1 see these links
