  1. Im going to build a pc and i want to put windows 8 on it can i just buy a windows 8 oem or do i have to buy windows 7 and then install windows 8 upgrade

  2. omg, this is perfect, i accidently bought the upgrade for my new computer, i installed it without any previous software, will this work if it’s a new computer?

  3. Would this work on a new computer (newly built)? Download Windows 8 from different computer (off internet). Convert to ISO/USB then plug in to new computer (with nothing on it).?

  4. Just one thing: you don’t really need to do the registry hack in order to do a clean install if you’ve got Windows XP/Vista/7 installed on the same hard drive you’re installing Windows 8 to. Just follow the procedures in the video except for the registry hack. See that’s why Windows 8 setup requires you to enter a valid product key before it even starts installing. It detects your existing copy of Windows and activates Windows 8 automatically once it boots for the first time.

  5. Bid thanks Paul, I used Windows 8 Enterprise Edition 64bit (free developer download), and using the run Windows XP Mode to get upgrade. Paid £24.99 (about $40). Needed the registry edit to get the upgrade to work from the ISO. Also I find Classic Shell a must to make it work like XP / Windows 7 Start button. Top job mate, big thanks for the video.
