Windows 7 Home Premium SP1 64bit, System Builder OEM DVD 1 Pack (New Packaging)

I have a Toshiba laptop that is 6 years old (2008) that came with Vista that is still pretty powerful. After I got it, I installed a Linux distribution on it and have been using Linux until now, but decided I wanted to go back to Windows (my wife's is Win 8.1, which I like). I researched on Toshiba and Microsoft websites as well as other sites, to whether I could upgrade to Win 8.1. Based on the architecture (no UEFI / secure boot), it appeared I could only go to Win 8, not Win 8.1. Since I am not a fan of 8, I decided to upgrade to Win 7. I reinstalled Vista (a real pain), but I wanted to do a "clean install". This DVD went in smoothly, and allowed to do exactly what I wanted: Wipe the disk clean, create a partition for Win 7, and install. It went fast, and after multiple Windows Update batches and reboots, my laptop works like a charm -- fast boot, great performance. - Customer Reviews
