Win 7 not genuine issue

I bought it from HP to replace the corrupted VISTA that came with the computre. The problem was that I did a clean install with an Upgrade product. A few hours on the phone with Microsoft Tech Support fixed the problem.
Frankly I wish I had stuck with reloading the VISTA - after years using Outlook Express I am lost without it!. I bought a copy Of MS Office from Staples because the guy told me it had a mail program. All it did was take me back to Hotmail which I already had. Thanks to all for their help! Capn Gene
