Hello. I had a hard disk failure and had to replace it. I have no media to recover the Windows 7 installation and foud out with Microsoft that the correct Windows 7 Home Premium OA version for me to activate can only be obtained from HP.
From what they said my activation key wouldnt work with another version.
I do have my computer serial and also my Windows tag with its serial and activation code, but could not find this Windows version for download in the product support software page.
