Windows 7 Re-installation


Well-Known Member
I had purchased Windows 7 upgrade about 2 years ago, downloaded and saved it as an ISO CD. I just had to format my hard drive and re-install. The installation completed but never asked for my Key Code. I checked Control Panel > System and found a temporary key code valid only for 15 days. When I changed the key code, I was advised of a "failure" because this Windows 7 was an "upgrade." Yes, I had upgraded from XP. Must I re-install XP and then install W-7 as an upgrade? Is there any way around this issue?

Did you reformat during the install, or prior to starting the re-install?

This is one of the situations that has been hanging since Microsoft decided to change the way upgrades were handled. But if you did a custom install and the old install was still on the drive, I would call them and check.

If you wiped the drive prior to starting the install, not really sure what the situation might be. The fact it only gave you a 15 day window might mean something.

Anyway, let us know, if you would...
