Hi,
When MSFT was selling Win7 Home Premium Upgrades for $50, I bought two
because I had a desktop and a laptop with OEM (Dell) installed Vista that
I wanted to 'upgrade'. Actually, I wanted to do clean installs.
On both machines, I reformatted the hard drives so they we rid of Vista,
and I did a 'custom' install of the Win 7 upgrade. I got lucky both
times. Funny thing is, I did not have to activate the desktop but the
laptop asked for activation in a couple of months.
It sounds like you basically did this (with a slipstream of SP1), here:
http://windowssecrets.com/top-story/...ws-7-from-the-
upgrade-disc/
"The short version of that trick is this: Once you’ve installed Win7 from
the upgrade DVD, start Win7, and then stick the upgrade disc in the drive
again. Follow the instructions to upgrade, but don’t choose Custom —
you’re upgrading to Windows 7 from Windows 7. Enter the key when
requested, and it’ll validate the next time you’re online."
I had such a hard time applying SP1 to the laptop, that I still haven't
installed SP on the desktop. Maybe I'll get brave this weekend.
