I have a Win7 64Bit Home Premiume Disc I got fro Microsoft with the Product Key.
I put this on all of my PCs that I make.
But now I have a Dell that I got with win7 64Bit Home Premiume installed on it.
I wanted to do a Non Destructive Repair Install of win7 with the one I have.
So I Logon as Administrator and go into Windows Updats and I see in the List Service Pack 2.
Now I know I should Delete this before I go on but I left it.
Because the Win7 Disc I have just has Service Pack 1.
So I put my Dick in and let it startup on my Desktop.
And yes I click Upgrade and it does it and keeps all my Programs and files.
And it restarts a fue times.
All is good but one thing.
I go to Activate it and I try to use my Product key that came with my Win7 I got and no good.
So I got the system product key at the start just as a baskup incass.
I used Jelly Bean to get my system Produck key.
So now I try that key and no good.
I know I got a Dell system and it came with win7 installed on it and it is an OEM.
And yes I know Dell puts it on all there systems.
But is this because I did not Delete the service pack2 in the win updates list?
I did this before even though my system has win installed from Dell I do have a good copy of win7 and the same verson.
What am I missing?
