I bought a new laptop which came with windows 8 installed on it, naturally I want to do a reformat and reinstall to get rid of the bloatware etc, however when trying to download the ISO via the Microsoft website it says I can't use my oem key (which I had to use a 3rd party program to find
).
So where can I download a clean Windows 8 ISO?
Or am I better off just switching to Windows 7?
