My Dell could not take higher upgrades (ie 2008 and above) and I ran the advisor and compatability wizard before I bought the Windows 7 upgrade. I have since purchased an HP Pavillion, so my need to install the Windows 7 was not so urgent. I am now wondering how I can now install this upgrade (even though it too is soon to loose technical assistance from Microsoft) as I cannot locate the code sent, showing my purchase. Any ideas - I need to go somewhere to try and install, then be queried (have you got a code etc, say yes but forgotten it; then be send details how to retrieve or be re-send this code). If I hadn't bought the code, I wouldn't be bothered now - other than I like my Dell and will be gutted when I can no longer use it (nothing wrong with it, just the upgrades to the Program!!!! My mind is thus: - I have bought the upgrade, so now want to access it - and cannot locate an email or a download, so must have received a code, written it down on a note, and lost it! Any help is appreciated. My Dell didn't come with Windows 7, so no disk. The program was purchased from Microsoft, as I said, last year. I am now used to Windows 10, but Dell cannot be upgraded to that! Shame! Thanks, in advance of any help.
