Win 7 upgrade issues

Hey all,

This forum has a wealth of information & I really wish I'd read more of the info related to the different Win 7 versions before ordering the one I did, as I probably wouldn't be in my current predicament.
Here's hoping someone here can help as the MS people I spoke to were no help at all.

I purchased the student download edition of Win 7 to go with a new computer I'm building for myself for Christmas (didn't realise at the time all the limitations & complications involved with it being an "upgrade" version.)

When I finally figured out how to make an iso out of the files I'd downloaded I figured I'd go ahead & try it out on my existing machine (running XP 32-bit) so I could get familiar with the layout etc for when I would install it on my new pc.
That install went smoothly, and I think I activated the Win 7 install.
I've since found out that the key is restricted to one activation only?

Fast forward a month or so and I've built the new pc and went to install Win 7 on it.
It didn't accept my CD key on the initial install, so I left it blank then tried activating it once it was installed. No go.
Tried those workarounds (double-install & the registry edit) and still had no luck.

I'm assuming the reason for it not activating is that my key that I got with the download was already used to activate Win 7 on my old machine.

Is there some way I can "deactivate" that activation, so I can activate it on the new machine? That old machine is relegated to the junk pile in the garage, and likely won't ever be used again.

Thanks in advance for any advice!

There's no explicit deactivation. All that you're supposed to do is uninstall it from the old system.

You may have to activate the new install by phone. There are two levels of that: the first is fully automated. You ought to be able to get through that by supplying the right answer when asked how many systems Windows is installed on (one). If that doesn't work, you'll be transferred to a live Microsoft representative. Total time: 5-10 minutes.

Does Windows have a specific "uninstall" option, or is it just a matter of formatting the drive?
I've uninstalled plenty of stuff using the add/remove software option from the control panel, but never thought of looking to see if Windows could be uninstalled from there.

Thanks for the advice. I imagine a call to MS will be in order.

Hopefully they will be more helpful than "Raj" who I spoke to the other night was!

Well this is odd.

I tried the auto-activate when I got home, and once again it didn't work.
However, when I chose the activate by phone option, it gave me the activation code after I'd put in my install code. Strange, as it's the exact same thing I'd tried the past few nights with no success.

Now off to copy all my pics, music from the old machine before I format it.

Thanks again for all the help.

So they have the same level of automation as with XP/Vista: if they have no record of prior hardware config/MAC address being overwritten with a new key, then they assume it is possibly on more than one computer. This requires the robocall where they deactivate on old machine and activate on new one.

You think they could get the internet activation to do that, but there is some reason they want a phone call - maybe Caller I.D. in case it turns out to be heavily pirated key? But they have the ISP anyway.
