I just purchased this W7 Pro upgrade.....here http://www.hotukdeals.com/item/519109/microsoft-windows-7-professional-up?page=3
And at present I'm using an Acer M3600 with Windows Vista...............but I have no disks.
With the above purchase will I only be able to install as a upgrade or will I be able to do a clean install? I have not used or know the how to's of installing W7 but have read some threads that mention it is a possiblity.
Thanks in advance for answers
