**Updated**
Ok, so I tried to reinstall XP on my computer (see original post below) and could not do it due to my 2002 issued XP CD causing a BSOD during setup on my new machine. So, I could not reinstall XP to then install Windows 7 on top of, which was a blessing in disguise. This forced me to call back into MS support and because it was a different problem now I was elevated to the next level of tech support. Here is where it gets good.
The very friendly support tech asked me to explain the issue, afterward he said that he would make sure I had a working version of Windows 7 by the end of our call. I cannot overstate the friendly nature of this person and how he worked to understand my issue and resolve it. 5 Stars for him.
Anyway, he first says that we have to remove the registry flag that was causing the invalid product code error. This flag was set during installation when I tried to enter it during the setup process, but more about that in a minute. Once the flag was removed with the msdt application (support has to give you a code for this tool), I was asked to reboot. When the system came back up I was prompted to enter the product code I re-entered the code from the product package and it worked! After reboot to verify, everything was working without re-installing Windows XP.
Here is the important lesson I learned from the tech support guy.
Do NOT enter the product code during the initial installation process, just skip the dialog by leaving it blank and finish the installation. It is at this point where the registry flag is set if an existing windows installation is not present. If you skip it the activation system will not check for a previous install since it would have been wiped at this point. That’s how you can install an upgrade version onto a blank or recently formatted hard drive.
If I would have been told this the first time I called, the rest of what you see below would have never been written.
Advice to Microsoft, give these instructions to your first level tech support. Never tell someone to reinstall XP to install Windows 7, that is just rude and frustrating for your customers.
Now, I am off to see what I think about Windows 7. I hope the rough start is not a sign of things to come.
WIN!

So, I decided today to sell a little bit of my soul and ‘Upgrade’ to Windows 7 Professional from Windows XP.
As a happy OS X user in the office, and a satisfied Ubuntu Linux user at home, I decided that I should give Windows a try again on my home office workstation.
I went to Best Buy and sacrificed ~$200 for the Windows 7 Professional Upgrade package. This left a mark, but I am willing to take a gouge in my wallet now and again for the sake of ‘Progress’. I have had Windows XP for over 10 years and skipped the whole Vista transition (gladly), so I felt it was time to re-familiarize myself with MS technologies and see what I am missing. ( I have learned in the few short hours since purchasing that I have only missed out on some suffering and time suck so far.)
Here is where the EPIC FAIL Windows 7 Upgrade begins…
I read on the back of the box that for upgrading from XP I need to backup all of my files and settings, and then perform a ‘clean install’ and then re-install my stuff from before. Easy enough, and hey if I need to do a clean install, then a blank hard drive doesn’t get any cleaner right? Nope, here is where the word ‘clean’ gets tricky. What the brilliant graphic designers for the box didn’t mention is that Windows 7 wants to clean the disk for you, after it detects that XP is already on the system. Having a pretty hologram CD and a valid product key on the XP package won’t save you here folks if you happen to ‘clean’ the disc with a full format before installing Windows 7. Trust me, I talked to 3 people at Microsoft support about this (hello hold times). You see, without already having XP Service Pack 3 on your system, there is nothing they can do to help me. F^#K (Frak) So, what does this mean to me as a consumer.
I now, after already burning time to do my own version of a clean install and spending $200 on the ‘upgrade’, have to go back and start from scratch, by reinstalling XP and doing all of the system updates to Service Pack 3. I am not kidding… or joking… or even smiling at this point. If you have recently performed a complete re-installation of XP from disc, you already know about the massive time suck that I am about to engage in. Let’s just say… “This is gonna take a while”. And then, I will get the joy of reinstalling Windows 7 again after all that! Yea!!! (not really)
I have learned a lesson the hard way, and I want to pass along some wisdom to all of you who might be planning to follow in my path of misery and time wastage.
Advice to those considering the upgrade… please don’t be smart and use your skills to prepare your hard drive for a ‘clean install’ by formatting it first. Or, if you decide that along with your fancy new Windows 7 Professional purchase, you should pick up a shiny new HDD to go with it, because your old one had not been upgraded in about 5 years. Don’t you will be sad about things later as you reinstall XP.
Advice to Microsoft, find a way to allow honest customers who waste their time and money on your new products to upgrade from existing product codes if they have a new blank hard disk or a recently formatted one. Forcing anyone to reinstall XP from scratch sucks and I wouldn’t wish it on anyone. This is not a difficult problem, just get the existing product code from XP and validate it, if it is good, then use it to activate the new Windows 7 with the product code from the new package. Then tell your customer that yes indeed there is help and of course the ranting post on bryanklein.com is out of date and that they will not need to reinstall XP from scratch. I mean seriously, how insane would that be right?… right?!
(Note: this was written while using the initial non-activated install of Windows 7 Professional, just before I started the painstaking process of ‘upgrading’ to Windows 7 Professional.)
FRAK!
