I recently tried to upgrade a PC to Windows 8, however, due to problems with crackling on the sound output I decided to return to Windows 7 (and yes, I did install the motherboard and soundcard drivers).
My copy of Windows 7 is an upgrade edition, meaning I have to do a clean install on the Windows 8 drive to return to Windows 7 as Windows 8 is recognised by the Windows 7 installation disk as a newer version of Windows. I thus need to delete the partition on which Windows 8 was installed to achieve this.
I was therefore faced with the situation of installing my upgrade edition of Windows 7 on a completely blank hard drive. It installed, however, on reaching the product key entry screen it rejected my product key (i.e. where you enter xxxxx-xxxxx-xxxxx-xxxxx-xxxxx). Note I am NOT talking about Windows online activation and, yes, I did enter the product key correctly.
In order to persuade Windows 7 to install, I thus seem to need to do one of two things:
1) Install an older version of Windows first (I happen to have an old XP installation disk); or
2) Buy a clean install product key.
I have, however, read about double install. Does this mean if I install Windows 7 on itself (i.e. upgrade from Windows 7 to Windows 7), it will recognise my product key?
Many thanks in advance,
