Windows 7: Doing a Clean Install with a Upgrade Windows 7 Version

Clean Install didn't work with Upgrade Media

I had the same problem. Installed fine on a brand new clean HDD, but product key came up as "Invalid Key". Called Microsoft. They said that because no previous OS on the drive, the key wouldn't activate.

Rather than go through the rigamarole of Option 3, I just loaded an old copy of XP, and then did the re-install of Windows 7 Upgrade --> Worked perfectly.

So, if you have an old XP or Vista disc lying around, and don't mind the extra 45-60 minutes to load it first, it will save you a registry hack!

Just my 2 cents.

Why would reinstalling XP or Vista be easier than doing a 20 second REgistry edit or running an Upgrade of WIn7 over itself to get it to accept Upgrade version key?

All of this is on the honor system anyway. There is no "legal way" of upgrading, only the EULA requirement that you have Vista or XP on hand to use WIn7 Upgrade version, and do not use the qualifying OS after 7 install.

These workarounds have been in effect since Vista release to make it easier to install/reinstall Upgrade version.

Some are mired in XP oldthink that the installer is smart enough to audit what OS is on your HD. It passes the key to allow Upgrade version key if it sees any OS on the computer, including Win7 itself.

When you boot the Win7 installer, it scans the HD to see any OS which then passes a flag to allow Upgrade version key.

If you ran it from Vista then you are already in it so it allows Upgrade key, of course, whether you in-place Upgrade or Custom overwrite or to another partition or HD.

RE: The Family Pack 7 Upgrade (re-released copy)

Folks:

Just out of curiosity, does the Windows 7 clean install with an upgrade still work (i.e., from the re-released medium of the Family Pack 7 Upgrade?)

Here's a more interesting question:

Does a Clean Install with Upgrade Media work one more than one computer (IE can I use the same product key for more than one Win7 installation, on two different computers)?

Hello AxeluteZero,

No. You can only activate one Windows 7 computer using the same product key number at any one time. Any previous installation with that same key number will have to be uninstalled first, and you may have to do a phone activation.

With VISTA, you could not install a fresh copy, you needed to upgrade your existing OS. (unlike XP, 2000, etc.) Did this change with 7? Can you do a clean install from an upgrade 7 DVD? Thanks!
