I recently had to buy a new copy of W7 (since I could not face reinstalling Vista - W7 Home upgrade - W7 Ultimate upgrade, which was what I was using until Windows Explorer died on me). Fortunately I had 2 hard discs on a nice large machine, installed the new copy, bought on Amazon on disk D, and still had all my old files accessible without reloading them etc. (Yes of course I had to re-install a number of programs, but I knew it wouldn't be entirely painless)
Now - two weeks later - Microsoft tells me that my new copy of W7 Ultimate is not genuine and blocks the product key. I have asked the supplier for any info and am waiting for Microsoft (whom Heaven preserve for a worse fate than I think of right now) to tell me what is going on.
I have been told however by a mate that I might have an MSDN version of W7 - thanks to you I now understand something of what that is. My question is, if Microsoft doesn't raise any objections, can I continue to use it for "ordinary" things like Excel, Word, the odd small BASIC program and statistical packages - and occasionally finding things on the net with Mozilla - I am a semi-retired statistician, and teach English on the side, and have no real interest nowadays in programming, still less in Developing Applications. Nor do I want to use Photoshop or Youtube or stream things (whatever that is). Can I use it or will it blow up in my face?
