I purchased the upgrade.
Is it possible for me to install Fresh?
I have got an iso then put in the ms generic code and then change it to my key?
But surley windows would say that my key is for an upgrade version only?
Any help would be great.

Works fine I've done this,ie Win8.1 ISO for clean install ,used the generic Win8.1 key for initial install then used my legit Win8.1 upgrade key for activation after.

More info here if you have issues,http://answers.microsoft.com/en-us/windows/forum/windows_8-windows_install/windows-8-pro-upgrade-product-key-cant-be-used-to/1726d238-98fb-4634-a468-04645a8ee097


The work around for this, while probably not officially supported for obvious reasons (they want more money), is to change a registry key. This was posted for Windows 7 update keys doing the same thing on a forum (though I had an update version AND did a clean install MULTIPLE times without having to do this) but worked without an issue on my laptop running Windows 8 regardless.

1. Run the registry editor (regedit)
2. Find the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\OOBE
3. Change the value for 'MediaBootInstall' from 1 to 0
4. Open an elevated command prompt (run as admin)
5. Run the following command: slmgr -rearm
6. Reboot

If you already entered your key, check the activation: for me it was already activated and I needed to do nothing more. If not, type in activate windows and type in the key; it should work. Also, do yourself a favor and export this key from regedit and save it somewhere if you ever are required to do another clean install. I know I did.

Exactly what I am doing, I need IE9 for something so I need W7 to run it on, W8 and W7 run great in dual boot.
